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.
