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 );
libc
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.
