ldrseek or ldnrseek Subroutine

Purpose

Seeks to the relocation entries of a section of an XCOFF file.

Library

Object File Access Routine Library (libld.a)

Syntax

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

int ldrseek ( ldPointer, SectionIndex) ldfile *ldPointer; unsigned short SectionIndex;

int ldnrseek (ldPointer, SectionName) ldfile *ldPointer; char *SectionName;

Description

The ldrseek subroutine seeks to the relocation entries of the section specified by the SectionIndex parameter of the common object file currently associated with the ldPointer parameter.

The ldnrseek subroutine seeks to the relocation entries of the section specified by the SectionName parameter.

For AIX 4.3.2 and above, both subroutines determine the object mode of the associated file before seeking to the relocation entries of the indicated section.

Parameters

ldPointer	Points to an LDFILE structure that was returned as the result of a successful call to the ldopen, lddopen, or ldaopen subroutines.
SectionIndex	Specifies an index for the section whose relocation entries are to be sought.
SectionName	Specifies the name of the section whose relocation entries are to be sought.

Return Values

The ldrseek and ldnrseek subroutines return a SUCCESS or FAILURE value.

The ldrseek subroutine fails if the contents of the SectionIndex parameter are greater than the number of sections in the object file. The ldnrseek subroutine fails if there is no section name corresponding with the SectionName parameter. Either function fails if the specified section has no relocation entries or if it cannot seek to the specified relocation entries.

Note: The first section has an index of 1.

Implementation Specifics

These subroutines are part of Base Operating System (BOS) Runtime.
