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 stucture 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.
