resmgr_iofuncs()

Extract the I/O function pointers associated with client connections

Synopsis:

#include <sys/resmgr.h>

const resmgr_io_funcs_t * resmgr_iofuncs(
   resmgr_context_t * ctp;
   struct _msg_info * info);

Arguments:

ctp

A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.

info

A pointer to the _msg_info structure that describes the binding to the client. You should fill this structure by calling MsgInfo().

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The resmgr_iofuncs() function retrieves the I/O function callout table associated with the client connections described by binding specified by info.

Note that context information pointed to by ctp actually contains info.

Returns:

A pointer to the resmgr_io_funcs_t I/O function callout table, or NULL if the binding can't be found or an error occurs.

Errors:

ESRCH

The connection can't be located in the resource manager's table.

ENOMEM

There is no memory available for the operation.

EINVAL

Invalid arguments were used.

Classification:

QNX Neutrino
