Default handler for _IO_PATHCONF messages
#include <sys/iofunc.h> int iofunc_pathconf_default( resmgr_context_t *ctp, io_pathconf_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_pathconf_t structure that contains the message that the resource manager received. For more information, see the documentation for iofunc_pathconf().
- 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_pathconf_default() function implements POSIX semantics for the client's pathconf() call, which is received as an _IO_PATHCONF message by the resource manager.
You can place this function directly into the io_funcs table passed to resmgr_attach(), at the pathconf position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
The iofunc_pathconf_default() function returns information about the resource, as per the POSIX specifications for pathconf(). The iofunc_pathconf_default() function simply calls iofunc_pathconf() to do the actual work.
- Successful completion.
- The pathconf parameter being ascertained wasn't one of _PC_CHOWN_RESTRICTED, _PC_NO_TRUNC, or _PC_SYNC_IO.
