iofunc_chmod_default()

Default handler for _IO_CHMOD messages

Synopsis:

#include <sys/iofunc.h>

int iofunc_chmod_default( resmgr_context_t *ctp,
                          io_chmod_t *msg,
                          iofunc_ocb_t *ocb );

Since:

BlackBerry 10.0.0

Arguments:

ctp
A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
msg
A pointer to the io_chmod_t structure that contains the message that the resource manager received. For more information, see the documentation for iofunc_chmod().
ocb
A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.

Library:

libc

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

Description:

The iofunc_chmod_default() function implements POSIX semantics for the client's chmod() call, which is received as an _IO_CHMOD message by the resource manager.

You can place this function directly into the io_funcs table passed to resmgr_attach(), at the chmod position, or you can call iofunc_func_init() to initialize all the functions to their default values.

The iofunc_chmod_default() function calls iofunc_chmod() to do the actual work.

Returns:

EOK
Successful completion.
EROFS
An attempt was made to chmod() on a read-only filesystem.
EACCES
The client doesn't have permissions to do the operation.
EPERM
The group ID or owner ID didn't match.

Classification:

QNX Neutrino
