SYNOPSIS

10       #include <corosync/cmap.h>
11
12
13       cs_error_t  cmap_iter_init  (cmap_handle_t  handle, const char *prefix,
14       cmap_iter_handle_t *cmap_iter_handle);

DESCRIPTION

18       The cmap_iter_init function is used to initialize iteration of all keys
19       with  given prefix.  The handle argument is connection to CMAP database
20       obtained by calling cmap_initialize(3) function.  prefix is string, and
21       every  returned key must have name with given prefix. This variable can
22       also be NULL (or empty string) and then all keys are iterated.
23
24       cmap_iter_init  is  used  only  for  initialize  context   for   future
25       cmap_iter_next(3) calls and handle needed for that function is returned
26       in cmap_iter_handle variable. When you  have  finished  iteration  over
27       objects,  call cmap_iter_finalize(3) function to free up memory associā€
28       ated with iteration.

RETURN VALUE

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