CMAP_ITER_INIT(3) Corosync Cluster Engine Programmer's Manual

NAME

cmap_iter_init - Initialize iterator for keys stored in CMAP

SYNOPSIS

#include <corosync/cmap.h>


cs_error_t cmap_iter_init (cmap_handle_t handle, const char *prefix,
cmap_iter_handle_t *cmap_iter_handle);

DESCRIPTION

The cmap_iter_init function is used to initialize iteration of all
keys with given prefix. The handle argument is connection to CMAP
database obtained by calling cmap_initialize(3) function. prefix is
string, and every returned key must have name with given prefix. This
variable can also be NULL (or empty string) and then all keys are
iterated.

cmap_iter_init is used only for initialize context for future
cmap_iter_next(3) calls and handle needed for that function is
returned in cmap_iter_handle variable. When you have finished
iteration over objects, call cmap_iter_finalize(3) function to free
up memory associated with iteration.

RETURN VALUE

This call returns the CS_OK value if successful. If there are no
items with given prefixes, CS_ERR_NO_SECTIONS is returned.
