.SH NAME
.P
cmap_iter_next \- Return next item in iteration in CMAP
.SH SYNOPSIS
.P
\fB#include <corosync/cmap.h>\fR
.P
\fBcs_error_t
cmap_iter_next(cmap_handle_t \fIhandle\fB, cmap_iter_handle_t \fIiter_handle\fB, char \fIkey_name[]\fB,
size_t *\fIvalue_len\fB, cmap_value_types_t *\fItype\fB);\fR
.SH DESCRIPTION
.P
The
.B cmap_iter_next
function is used to get next value in iteration. The
.I handle
argument is connection to CMAP database obtained by calling
.B cmap_initialize(3)
function.
.I iter_handle
argument is iterator handle obtained by
.B cmap_iter_init(3)
function. Following key name is stored inside
.I key_name
argument, which must be preallocated by caller and its guaranteed maximum size is CMAP_KEYNAME_MAXLEN
(currently 255).
.I value_len
is pointer where length of value is stored, but can be NULL.
.I type
is also optional argument (can be NULL) and here type of value is stored (type is one of types described
in
.B cmap_get(3)
function).
.SH 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.
