Default handler for _IO_CHMOD messages
#include <sys/iofunc.h> int iofunc_chmod_default( resmgr_context_t *ctp, io_chmod_t *msg, iofunc_ocb_t *ocb );
- A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
- 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().
- A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
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.
- Successful completion.
- An attempt was made to chmod() on a read-only filesystem.
- The client doesn't have permissions to do the operation.
- The group ID or owner ID didn't match.
