The _overview manpages are not actually commands and hence do not belong
into manpage section 8. Move corosync_overview to section 7
("Miscellaneous") and the other *_overview pages to section 3 as they
contain API documentation (cf. string(3) for precedence of
multi-function manpages).

.SH NAME
|
|
.P
|
|
cmap_dispatch \- Dispatches callbacks from the CMAP service
|
|
|
|
.SH SYNOPSIS
|
|
.P
|
|
\fB#include <corosync/cmap.h>\fR
|
|
|
|
.P
|
|
\fBcs_error_t
|
|
cmap_dispatch (cmap_handle_t \fIhandle\fB, cs_dispatch_flags_t \fIdispatch_types\fB);\fR
|
|
|
|
.SH DESCRIPTION
|
|
The
|
|
.B cmap_dispatch
|
|
function is used to dispatch configuration changes.
|
|
.PP
|
|
Each application may have several connections to the CMAP API. Each application
|
|
uses the
|
|
.I handle
|
|
argument to uniquely identify the connection.
|
|
.PP
|
|
The
|
|
.I dispatch_types
|
|
argument is used to identify the type of dispatch to execute. The possible types are
|
|
CS_DISPATCH_ONE, CS_DISPATCH_ALL and CS_DISPATCH_BLOCKING.
|
|
|
|
The dispatch values have the following meanings:
|
|
.TP
|
|
.B CS_DISPATCH_ONE
|
|
Dispatch at least one callback, blocking until the callback is dispatched.
|
|
.TP
|
|
.B CS_DISPATCH_ALL
|
|
Dispatch all waiting callbacks without blocking to wait for any callbacks.
|
|
.TP
|
|
.B CS_DISPATCH_BLOCKING
|
|
Dispatch all callbacks blocking indefinitely. This is used in a threaded
|
|
program where a thread is created, and then cs_dispatch() is called immediately
|
|
from the created thread to execute callbacks.
|
|
.TP
|
|
.B CS_DISPATCH_ONE_NONBLOCKING
|
|
Dispatch at most one callback. If there is no pending callback,
|
|
CS_ERR_TRY_AGAIN is returned.
|
|
.PP
|
|
It's needed to call
|
|
.B cmap_track_add(3)
|
|
to add tracked items and receive callbacks.
|
|
|
|
.SH RETURN VALUE
|
|
.P
|
|
This call returns the CS_OK value if successful, otherwise an error is returned.
|
|
|
|

|
.BR cmap_track_add (3),
|
|
.BR cmap_track_delete (3),
