Syntax

  #include <unistd.h> 
   
  long fpathconf (
     int   fildes,
     int   name);

fildes: (IN) Specifies an open file descriptor.
name: (IN) Specifies a pathname variable to be queried in the file specified by the fildes parameter. For a list of supported variables, see Path Configuration Variables

If successful, returns the value of the variable specified by the name parameter. Otherwise, returns -1 and sets errno to one of the following:

Decimal	Constant	Description
4	EBADF	Invalid file descriptor.
6	EACCES	Search permission is denied.
9	EINVAL	The value of name is not valid, or not valid for the specified file.

The fpathconf function can return -1 without setting a value in errno if the value of any of the name flags is unspecified.
