Due to extensive macros use, it is often +difficult to even find whole function, much less to understand what they +actually do. One way to find such a macro-defined function is to compile the +code with debugging symbols (-g), load the binary into gdb and set a breakpoint +for such a function. gdb will print out exact place in the code where the +function is defined. Presumably one will find a macro at that specific location. +For example to find where \ref lease_reference function is defined do: + +@verbatim +gdb +file dhcpd +b lease_reference +@endverbatim |
