.SH Description
The 
.PN ldrseek
function seeks to the relocation entries of the section specified by
.I sectindx
of the common object file
currently associated with
.IR ldptr .
.PP
The 
.PN ldnrseek
function seeks to the relocation entries of the section specified by
.IR sectname .
.PP
The functions 
.PN ldrseek
and
.PN ldnrseek
returns success or failure.
If 
.I sectindx
is greater than the number of sections in the object file,
.PN ldrseek 
fails;
if there is no section name corresponding with
.IR sectname,
.PN ldnrseek
fails.
If the specified section does not have relocation entries or
if it cannot seek to the specified relocation entries,
either function fails. 
.NT
The first section has an index of
.IR one .
.NE
