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.
