ldfhread(3) — Subroutines
NAME
ldfhread − read the file header of a common object file
SYNOPSIS
#include <stdio.h>
#include <filehdr.h>
#include <syms.h>
#include <ldfcn.h>
int ldfhread (ldptr, filehead)
LDFILE ∗ldptr;
FILHDR ∗filehead;
DESCRIPTION
ldfhread reads the file header of the common object file currently associated with ldptr . It reads the file header into the area of memory beginning at filehead.
ldfhread returns SUCCESS or FAILURE. If ldfhread cannot read the file header, it fails.
Usually, ldfhread can be avoided by using the macro HEADER(ldptr) defined in <ldfcn.h> (see ldfcn(4)). Note that the information in HEADER is swapped, if necessary. The information in any field, fieldname, of the file header can be accessed using HEADER(ldptr).fieldname .
The program must be loaded with the object file access routine library
