.SH NAME
readproc, freeproc  \- read information from next /proc/## entry
.SH SYNOPSIS
.B #include <proc/readproc.h>
.sp
.BI "proc_t* readproc(PROCTAB *" PT ", proc_t *" return_buf ");"
.br
.BI "void freeproc(proc_t *" p ");"

.SH DESCRIPTION

.B readproc
reads the information for the next process matching the criteria
specified in
.I PT
and fills them into a
.I proc_t
structure. If
.I return_buf
is not NULL, it will use the struct pointed at by
.IR return_buf .
Otherwise it will allocate a new
.I proc_t
structure and return a pointer to it.
Note that (if so specified in
.IR PT )
readproc always allocates memory if it fills in the
.IR environ " or " cmdline
parts of
.IR proc_t .

.B freeproc
frees all memory allocated for the
.I proc_t
struct
.IR *p .

The
.I proc_t
structure is defined in
.IR <proc/readproc.h> ,
please look there for a definition of all fields.

.SH "RETURN VALUE"

.B readproc
returns a pointer to the next
.I proc_t
or NULL if there are no more processes left.
