fpathconf 

Returns configuration variable for file descriptor. 

Syntax 

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

Parameters 

fildes     is an open file descriptor for the file or directory of which
           you want to determine the configuration variables.

name       is a symbol indicating the variable, the value of which you
           want to determine.

Return Values 

variable value   fpathconf() lets you determine the value of a
                 configuration variable associated with a particular file
                 descriptor.  If fpathconf() can determine the value of
                 the requested variable, it returns that value as its
                 result.

-1               If fpathconf() cannot determine the value of the
                 specified variable, it returns -1 and sets errno

fpathconf() works exactly like pathconf(), except that it takes a file
descriptor as an argument rather than a path name.  For further details,
see pathconf().

Errors 

If an error occurs, errno is set to one of the following values:

EBADF             CAUSE           fildes was not a valid file descriptor.
                  ACTION          Specify a valid file descriptor.

EINVAL            CAUSE           Name was not a valid variable code, or the given
                                  variable cannot be associated with the specified
                                  file.
                  ACTION          Specify a valid variable code.
