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.
