In general, you cannot as there is not a one-to-one map between fd's and filenames. Each file descriptor may represent zero, one, or more "file names" on the system. Besides, you already have the filename as it must have been used earlier in the program during an open(2) call.

ldap_friendly_name
ldap_friendly(3LDAP) LDAP Library Functions ldap_friendly(3LDAP)
NAME
ldap_friendly, ldap_friendly_name, ldap_free_friendlymap - LDAP attribute remapping functions
SYNOPSIS
cc[ flag... ] file... -lldap[ library... ]
#include <lber.h>
#include <ldap.h>
char *ldap_friendly_name(char *filename, char *name,
FriendlyMap **map);
void ldap_free_friendlymap(FriendlyMap **map);
DESCRIPTION
This function is used to map one set of strings to another. Typically, this is done for country names, to map from the two-letter country
codes to longer more readable names. The mechanism is general enough to be used with other things, though.
filename is the name of a file containing the unfriendly to friendly mapping, name is the unfriendly name to map to a friendly name, and
map is a result-parameter that should be set to NULL on the first call. It is then used to hold the mapping in core so that the file need
not be read on subsequent calls.
For example:
FriendlyMap *map = NULL;
printf( "unfriendly %s => friendly %s
", name,
ldap_friendly_name( "ETCDIR/ldapfriendly", name, &map ) );
The mapping file should contain lines like this: unfriendlyname friendlyname. Lines that begin with a '#' character are comments and are
ignored.
The ldap_free_friendlymap() call is used to free structures allocated by ldap_friendly_name() when no more calls to ldap_friendly_name()
are to be made.
ERRORS
NULL is returned by ldap_friendly_name() if there is an error opening filename, or if the file has a bad format, or if the map parameter is
NULL.
