NAME


Pdelwapt - remove a watchpoint in a process

LIBRARY

SYNOPSIS


#include <libproc.h>

int
Pdelwapt(struct ps_prochandle *P, const prwatch_t *wp);

DESCRIPTION


The Pdelwapt() function removes the watchpoint specified by wp from the
process represented by the handle P. The watchpoint should have been
installed with either Psetwapt(3PROC) or the underlying /proc file system
PCWATCH operation.

The Pdelwapt() function only works on running processes, such as those
created through Pgrab(3PROC) and Pcreate(3PROC). Attempting to remove a
watchpoint from process handles to core files, zombie processes, or ELF
objects will fail.

RETURN VALUES


Upon successful completion, the Pdelwapt() function removes the watchpoint
and returns 0. Otherwise, -1 is returned, errno is set to indicate the
error.

ERRORS


For a full list of possible errors see the DIAGNOSTICS section in proc(4).

The Pdelwapt() function will fail with:

ENOENT The handle P refers to a grabbed core file, a zombie
process, or an ELF object.
