.SH Description
The 
.PN ldlseek
function
seeks to the line number entries of the section specified by
.I sectindx
of the common object file
currently associated with
.IR ldptr .
.PP
The
.PN ldnlseek
function
seeks to the line number entries of the section specified by
.IR sectname .
.PP
The
.PN ldlseek
and
.PN ldnlseek
functions return success or failure.
.NT
Line numbers are not associated with sections in the MIPS
symbol table; therefore, the second argument is ignored, but maintained
for historical purposes.
.NE
If they cannot seek to the specified line number entries,
both routines fail.
