The following code obtains current values of configurable options of a file or directory whose vnode token is in VNODETOK. For the callable service, see v_pathconf (BPX1VPC, BPX4VPC) — Get pathconf information for a directory or file. For the data structures, see BPXYATTR — Map file attributes for v_ system calls, BPXYOSS — Map operating system specific information and Mapping macros in z/OS UNIX System Services Programming: Assembler Callable Services Reference.
