NAME¶
cpg_fd_get - Dispatches callbacks from the CPG service
SYNOPSIS¶
#include <corosync/cpg.h>
int cpg_fd_get(cpg_handle_t handle, int *fd);
DESCRIPTION¶
The
cpg_fd_get function is used to retrieve the file descriptor that may
be used with the poll system call to determine when
cpg_dispatch(3)
won't block. The
handle argument may not be used directly with
poll because it is not the file descriptor, but instead an internal
identifier used by the CPG library.
RETURN VALUE¶
This call returns the CPG_OK value if successful, otherwise an error is
returned.
ERRORS¶
The errors are undocumented.
