.SH DESCRIPTION
|
||
|
|
\fBprocps_pids_sort\fR sorts the given \fIstacks\fR stack of process
|
||
|
|
information and sorts it by the given \fIsortitem\fR. \fInumstacked\fR
|
||
|
|
must be the length of the \fIstacks\fR array and all the stacks in the
|
||
|
|
list must be homogenous (of equal length and content).
|
||
|
|
|
||
|
|
The stacks value can be obtained by a previous call of
|
||
|
|
.BR procps_pids_reap (3)
|
||
|
|
or
|
||
|
|
.BR procps_pids_select (3)
|
||
|
|
and then accessing the \fIstacks\fR member from that structure.
|
||
|
|
|
||
|
|
\fIorder\fR can be either PIDS_SORT_ASCEND or PIDS_SORT_DESCEND.
|
||
|
|
|
||
|
|
.SH RETURN VALUE
|
||
|
|
The function returns the sorted stack on success or NULL on failure.
