+.SH NAME
+unw_backtrace
+\-\- return backtrace for the calling program 
+.PP
+.SH SYNOPSIS
+
+.PP
+#include <libunwind.h>
+.br
+.PP
+int
+unw_backtrace(void **buffer,
+int size);
+.br
+.PP
+#include <execinfo.h>
+.br
+.PP
+int
+backtrace(void **buffer,
+int size);
+.br
+.PP
+.SH DESCRIPTION
+
+.PP
+unw_backtrace()
+is a convenient routine for obtaining the backtrace for 
+the calling program. The routine fills up to size
+addresses in the array 
+pointed by buffer\&.
+The routine is only available for local unwinding. 
+.PP
+Note that many (but not all) systems provide practically identical function 
+called backtrace().
+The prototype for this function is usually obtained 
+by including the <execinfo.h>
+header file \-\- a prototype for 
+backtrace()
+is not provided by libunwind\&.
+libunwind
+weakly 
+aliases backtrace()
+to unw_backtrace(),
+so when a program 
+calling backtrace()
+is linked against libunwind,
+it may end up 
+calling unw_backtrace().
+.PP
+.SH RETURN VALUE
+
+.PP
+The routine returns the number of addresses stored in the array pointed by 
+buffer\&.
+The return value may be zero to indicate that no addresses were 
+stored.
