READPROC(3) Linux Programmer's Manual READPROC(3)
NAME
readproc, freeproc - read information from next /proc/## entry
SYNOPSIS
#include <proc/readproc.h>
proc_t* readproc(PROCTAB *PT, proc_t *return_buf);
void freeproc(proc_t *p);
DESCRIPTION
readproc reads the information for the next process matching the crite-
ria specified in PT and fills them into a proc_t structure. If re-
turn_buf is not NULL, it will use the struct pointed at by return_buf.
Otherwise it will allocate a new proc_t structure and return a pointer
to it. Note that (if so specified in PT) readproc always allocates
memory if it fills in the environ or cmdline parts of proc_t.
freeproc frees all memory allocated for the proc_t struct *p.
The proc_t structure is defined in <proc/readproc.h>, please look there
for a definition of all fields.
RETURN VALUE
readproc returns a pointer to the next proc_t or NULL if there are no
more processes left.
