For each object created, a set of operations is available for +examining or changing its properties. + +Furthermore, complex data types, such as C structures, are represented +in a tree format. For instance, the @code{struct} type variable is the +root and the children will represent the struct members. If a child +is itself of a complex type, it will also have children of its own. +Appropriate language differences are handled for C, C@t{++} and Java. + +When returning the actual values of the objects, this facility allows +for the individual selection of the display format used in the result +creation. It can be chosen among: binary, decimal, hexadecimal, octal +and natural. Natural refers to a default format automatically +chosen based on the variable type (like decimal for an @code{int}, hex +for pointers, etc.). + +The following is the complete set of @sc{gdb/mi} operations defined to +access this functionality: + +@multitable @columnfractions .4 .6 +@item @strong{Operation} +@tab @strong{Description} + +@item @code{-var-create} +@tab create a variable object +@item @code{-var-delete} +@tab delete the variable object and its children +@item @code{-var-set-format} +@tab set the display format of this variable +@item @code{-var-show-format} +@tab show the display format of this variable +@item @code{-var-info-num-children} +@tab tells how many children this object has +@item @code{-var-list-children} +@tab return a list of the object's children +@item @code{-var-info-type} +@tab show the type of this variable object +@item @code{-var-info-expression} +@tab print what this variable object represents +@item @code{-var-show-attributes} +@tab is this variable editable? does it exist here? +@item @code{-var-evaluate-expression} +@tab get the value of this variable +@item @code{-var-assign} +@tab set the value of this variable +@item @code{-var-update} +@tab update the variable and its children +@end multitable + +In the next subsection we describe each operation in detail and suggest +how it can be used. + +@subheading Description And Use of Operations on Variable Objects + +@subheading The @code{-var-create} Command +@findex -var-create + +@subsubheading Synopsis + +@smallexample + -var-create @{@var{name} | "-"@} + @{@var{frame-addr} | "*"@} @var{expression} +@end smallexample + +This operation creates a variable object, which allows the monitoring of +a variable, the result of an expression, a memory cell or a CPU +register. + +The @var{name} parameter is the string by which the object can be +referenced.

System calls on the target system are translated into a +remote protocol packet to the host system which then performs the needed +actions and returns with an adequate response packet to the target system. +This simulates file system operations even on targets that lack file systems. + +The protocol is defined host- and target-system independent. It uses +it's own independent representation of datatypes and values. Both, +@value{GDBN} and the target's @value{GDBN} stub are responsible for +translating the system dependent values into the unified protocol values +when data is transmitted. + +The communication is synchronous. A system call is possible only +when GDB is waiting for the @samp{C}, @samp{c}, @samp{S} or @samp{s} +packets.

In this case the target should behave, as if it had +gotten a break message. The meaning for the target is ``system call +interupted by @code{SIGINT}''. Consequentially, the target should actually stop +(as with a break message) and return to @value{GDBN} with a @code{T02} +packet. In this case, it's important for the target to know, in which +state the system call was interrupted. Since this action is by design +not an atomic operation, we have to differ between two cases: + +@itemize @bullet +@item +The system call hasn't been performed on the host yet. + +@item +The system call on the host has been finished. + +@end itemize + +These two states can be distinguished by the target by the value of the +returned @code{errno}. If it's the protocol representation of @code{EINTR}, the system +call hasn't been performed. This is equivalent to the @code{EINTR} handling +on POSIX systems. In any other case, the target may presume that the +system call has been finished --- successful or not --- and should behave +as if the break message arrived right after the system call. + +@value{GDBN} must behave reliable. If the system call has not been called +yet, @value{GDBN} may send the @code{F} reply immediately, setting @code{EINTR} as +@code{errno} in the packet. If the system call on the host has been finished +before the user requests a break, the full action must be finshed by +@value{GDBN}. This requires sending @code{M} or @code{X} packets as they fit. +The @code{F} packet may only be send when either nothing has happened +or the full action has been completed. + +@node Console I/O +@subsection Console I/O +@cindex console i/o as part of file-i/o + +By default and if not explicitely closed by the target system, the file +descriptors 0, 1 and 2 are connected to the @value{GDBN} console. Output +on the @value{GDBN} console is handled as any other file output operation +(@code{write(1, @dots{})} or @code{write(2, @dots{})}). Console input is handled +by @value{GDBN} so that after the target read request from file descriptor +0 all following typing is buffered until either one of the following +conditions is met: + +@itemize @bullet +@item +The user presses @kbd{Ctrl-C}. The behaviour is as explained above, the +@code{read} +system call is treated as finished. + +@item +The user presses @kbd{Enter}. This is treated as end of input with a trailing +line feed. + +@item +The user presses @kbd{Ctrl-D}. This is treated as end of input. No trailing +character, especially no Ctrl-D is appended to the input. + +@end itemize + +If the user has typed more characters as fit in the buffer given to +the read call, the trailing characters are buffered in @value{GDBN} until +either another @code{read(0, @dots{})} is requested by the target or debugging +is stopped on users request. + +@node The isatty call +@subsection The isatty(3) call +@cindex isatty call, file-i/o protocol + +A special case in this protocol is the library call @code{isatty} which +is implemented as it's own call inside of this protocol. It returns +1 to the target if the file descriptor given as parameter is attached +to the @value{GDBN} console, 0 otherwise. Implementing through system calls +would require implementing @code{ioctl} and would be more complex than +needed. + +@node The system call +@subsection The system(3) call +@cindex system call, file-i/o protocol + +The other special case in this protocol is the @code{system} call which +is implemented as it's own call, too. @value{GDBN} is taking over the full +task of calling the necessary host calls to perform the @code{system} +call. The return value of @code{system} is simplified before it's returned +to the target. Basically, the only signal transmitted back is @code{EINTR} +in case the user pressed @kbd{Ctrl-C}. Otherwise the return value consists +entirely of the exit status of the called command. + +Due to security concerns, the @code{system} call is refused to be called +by @value{GDBN} by default.

For each object created, a set of operations is available for -examining or changing its properties. - -Furthermore, complex data types, such as C structures, are represented -in a tree format. For instance, the @code{struct} type variable is the -root and the children will represent the struct members. If a child -is itself of a complex type, it will also have children of its own. -Appropriate language differences are handled for C, C@t{++} and Java. - -When returning the actual values of the objects, this facility allows -for the individual selection of the display format used in the result -creation. It can be chosen among: binary, decimal, hexadecimal, octal -and natural. Natural refers to a default format automatically -chosen based on the variable type (like decimal for an @code{int}, hex -for pointers, etc.). - -The following is the complete set of @sc{gdb/mi} operations defined to -access this functionality: - -@multitable @columnfractions .4 .6 -@item @strong{Operation} -@tab @strong{Description} - -@item @code{-var-create} -@tab create a variable object -@item @code{-var-delete} -@tab delete the variable object and its children -@item @code{-var-set-format} -@tab set the display format of this variable -@item @code{-var-show-format} -@tab show the display format of this variable -@item @code{-var-info-num-children} -@tab tells how many children this object has -@item @code{-var-list-children} -@tab return a list of the object's children -@item @code{-var-info-type} -@tab show the type of this variable object -@item @code{-var-info-expression} -@tab print what this variable object represents -@item @code{-var-show-attributes} -@tab is this variable editable? does it exist here? -@item @code{-var-evaluate-expression} -@tab get the value of this variable -@item @code{-var-assign} -@tab set the value of this variable -@item @code{-var-update} -@tab update the variable and its children -@end multitable - -In the next subsection we describe each operation in detail and suggest -how it can be used. - -@subheading Description And Use of Operations on Variable Objects - -@subheading The @code{-var-create} Command -@findex -var-create - -@subsubheading Synopsis - -@example - -var-create @{@var{name} | "-"@} - @{@var{frame-addr} | "*"@} @var{expression} -@end example - -This operation creates a variable object, which allows the monitoring of -a variable, the result of an expression, a memory cell or a CPU -register. - -The @var{name} parameter is the string by which the object can be -referenced.
