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.
