.SH NAME
.P
cmap_fd_get \- Dispatches callbacks from the CMAP service

.SH SYNOPSIS
.P
\fB#include <corosync/cmap.h>\fR

.P
\fBcs_error_t
cmap_fd_get (cmap_handle_t \fIhandle\fB, int *\fIfd\fB);\fR

.SH DESCRIPTION
.P
The
.B cmap_fd_get
function is used to retrieve the file descriptor that may be used with the poll
system call to determine when
.B cmap_dispatch(3)
won't block.  The
.I handle
argument may not be used directly with
.B poll
because it is not the file descriptor, but instead an internal identifier used
by the CMAP library.

.SH RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned.

.SH "SEE ALSO"
.BR cmap_dispatch (3),
.BR cmap_overview (8)
