iofunc_chown_default()

Default handler for _IO_CHOWN messages

Synopsis:

#include <sys/iofunc.h>

int iofunc_chown_default( resmgr_context_t *ctp,
                          io_chown_t *msg,
                          iofunc_ocb_t *ocb );

Library:

libc

Description:

The iofunc_chown_default() function implements POSIX semantics for the client's chown() call, which is received as an _IO_CHOWN message by the resource manager. This function can be placed directly into the io_funcs table passed to resmgr_attach(), at the chown position.

The iofunc_chown_default() function calls iofunc_chown() 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 chown 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
