ldfhread(3x)               DG/UX 4.30                ldfhread(3x)



     NAME
          ldfhread - read the file header of an object file

     SYNOPSIS
          #include <stdio.h>
          #include <filehdr.h>
          #include <ldfcn.h>

          int ldfhread (ldptr, filehead)
          LDFILE *ldptr;
          FILHDR *filehead;

     DESCRIPTION
          Ldfhread reads the file header of the object file currently
          associated with ldptr into the area of memory beginning at
          filehead.

          Ldfhread returns SUCCESS or FAILURE.  Ldfhread will fail if
          it cannot read the file header.

          In most cases you can avoid using ldfhread by using the
          macro HEADER(ldptr) defined in ldfcn.h (see ldfcn (4)).  The
          information in any field, fieldname, of the file header may
          be accessed using HEADER(ldptr).fieldname or
          HEADER.(ldptr)sectionname.fieldname (for a field within a
          section descriptor).

          The program must be loaded with the object file access
          routine library libld.a.
