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 );

Library:

libc

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. This function can be placed directly into the io_funcs table passed to resmgr_attach(), at the chmod position.

The iofunc_chmod_default() function calls iofunc_chmod() to do the actual work, and (if installed in the io_funcs table) issues the reply back to the client.

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 6

Safety:
Cancellation point No
Interrupt handler No
Signal handler Yes
Thread Yes
