NAME

       cmap_iter_next - Return next item in iteration in CMAP

SYNOPSIS

       #include <corosync/cmap.h>

       cs_error_t  cmap_iter_next(cmap_handle_t  handle, cmap_iter_handle_t iter_handle, char key_name[], size_t
       *value_len, cmap_value_types_t *type);

DESCRIPTION

       The cmap_iter_next function is used to get next value in iteration. The handle argument is connection  to
       CMAP  database  obtained by calling cmap_initialize(3) function.  iter_handle argument is iterator handle
       obtained by cmap_iter_init(3) function. Following key name is stored inside key_name argument, which must
       be preallocated by caller and  its  guaranteed  maximum  size  is  CMAP_KEYNAME_MAXLEN  (currently  255).
       value_len  is  pointer  where length of value is stored, but can be NULL.  type is also optional argument
       (can be NULL) and here type of value is stored (type is one of types described in cmap_get(3) function).

RETURN VALUE

       This call returns the CS_OK value if successful. If there are no more  items  to  iterate,  CS_NO_SECTION
       error code is returned.
