iofunc_client_info()

Return information about a client connection

Synopsis:

#include <sys/iofunc.h>

int iofunc_client_info ( resmgr_context_t * ctp,
                         int ioflag,
                         struct _client_info * info );

Arguments:

ctp

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

ioflag

Zero, or the constant O_REALIDS. This argument is passed in the _IO_OPEN message during an open request. If O_REALIDS is specified, iofunc_client_info() swaps the real and effective values of the user and group IDs before returning. This is a QNX Neutrino extension, to swap real and effective user and group IDs in an atomic operation.

info

A pointer to a _client_info structure that the function fills with information about a client connection. For information about this structure, see ConnectClientInfo().

Library:

libc

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

Description:

The iofunc_client_info() function fetches the info structure for the client. It calls ConnectClientInfo() to gather the information, based on the server connection ID found in ctp->info.scoid.

Returns:

EFAULT

A fault occurred when the kernel tried to access the info buffer provided.

EINVAL

The client process is no longer valid.

EOK

Successful completion.

Classification:

QNX Neutrino
