ldfhread(3X)            LIBRARY FUNCTIONS            ldfhread(3X)



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  rou-
     tine library libmld.a.
