.SH NAME
procps_pids_reap \- Harvest all the PIDS information structure.
.SH SYNOPSIS
.B #include <proc/procps.h>
.sp
.BI "struct pids_fetch  * procps_pids_reap(struct pids_info *" info ", enum pids_fetch_type " which ");"
.sp
Link with \fI\-lprocps\fP.

.SH DESCRIPTION
\fBprocps_pids_reap()\fR is the function that will load the various
files in the
.BR proc (5)
filesystem and fill the returned structure with the parsed values as
well as a summary of the information gathered.
The function is able to parse only processes or also include threads, the
option \fIwhich\fR can be set to \fBPIDS_FETCH_TASKS_ONLY\fR or
\fBPIDS_FETCH_THREADS_TOO\fR to determine what is collected.

The info structure first needs to be initialised by
.BR procps_pids_new (3).
if \fBprocps_pids_reap()\fR returns successfully, a program can
then iterate through a loop using the accessor methods described in
.BR libproc (3).

.SH RETURN VALUE
\fBprocps_pids_reap()\fR returns a pointer to struct pids_fetch
on success and NULL on failure.

.SH VERSIONS
\fBprocps_pids_reap()\fR first appeared in libproc-2 version 0.0.
