.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.

\section{Description}
|
||||
|
||||
\Func{unw\_backtrace}() is a convenient routine for obtaining the backtrace for
|
||||
the calling program. The routine fills up to \Var{size} addresses in the array
|
||||
pointed by \Var{buffer}. The routine is only available for local unwinding.
|
||||
|
||||
Note that many (but not all) systems provide practically identical function
|
||||
called \Func{backtrace}(). The prototype for this function is usually obtained
|
||||
by including the \File{$<$execinfo.h$>$} header file -- a prototype for
|
||||
\Func{backtrace}() is not provided by \Prog{libunwind}. \Prog{libunwind} weakly
|
||||
aliases \Func{backtrace}() to \Func{unw\_backtrace}(), so when a program
|
||||
calling \Func{backtrace}() is linked against \Prog{libunwind}, it may end up
|
||||
calling \Func{unw\_backtrace}().
|
||||
|
||||
\section{Return Value}
|
||||
|
||||
The routine returns the number of addresses stored in the array pointed by
|
||||
\Var{buffer}. The return value may be zero to indicate that no addresses were
|
||||
stored.
