.SH Description
The
.PN ldsseek
seeks to the section specified by
.I sectindx
of the common object file
currently associated with
.IR ldptr .
.PP
The 
.PN ldnsseek
seeks to the section specified by
.IR sectname .
.PP
The
.PN ldsseek
and
.PN ldnsseek
return success or failure. If 
.I sectindx
is greater than the number of sections in the object file,
.PN ldsseek
fails;
if there is no section name corresponding with
.IR sectname,
.PN ldnsseek
fails.
If a no section data for the specified section does not exist or
if it cannot seek to the specified section, either function fails.
.NT
The first section has an index of
.IR one .
.NE
The program must be loaded with the object file access routine library
.BR libmld.a .
