Provided by: procps_3.3.12-3ubuntu1.2_amd64 bug

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.
