+.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.
