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 criteria specified in PT
       and fills them into a proc_t structure. If return_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.
