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 quaranted maximum size is CMAP_KEYNAME_MAXLEN (urrently 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. SEE ALSO
