#include <libunwind.h>

.SH DESCRIPTION
|
|
|
|
.PP
|
|
The unw_getcontext()
|
|
routine initializes the context structure
|
|
pointed to by ucp
|
|
with the machine\-state of the call\-site. The
|
|
exact set of registers stored by unw_getcontext()
|
|
is
|
|
platform\-specific, but, in general, at least all preserved
|
|
(``callee\-saved\&'') and all frame\-related registers, such as the
|
|
stack\-pointer, will be stored.
|
|
.PP
|
|
This routine is normally implemented as a macro and applications
|
|
should not attempt to take its address.
|
|
.PP
|
|
.SH RETURN VALUE
|
|
|
|
.PP
|
|
On successful completion, unw_getcontext()
|
|
returns 0.
|
|
Otherwise, a value of \-1 is returned.
|
|

|
|
.SH THREAD AND SIGNAL SAFETY
|
|
|
|
.PP
|
|
unw_getcontext()
|
|
is thread\-safe as well as safe to use
|
|
from a signal handler.
