ldlread(3x)ldlread(3x)Name
ldlread, ldlinit, ldlitem - manipulate line number entries of a common object file function
Syntax
#include <stdio.h>
#include <filehdr.h>
#include <syms.h>
#include <ldfcn.h>
int ldlread (ldptr, fcnindx, linenum, linent)
LDFILE *ldptr;
long fcnindx;
unsigned short linenum;
LINER linent;
int ldlinit (ldptr, fcnindx)
LDFILE *ldptr;
long fcnindx;
int ldlitem (ldptr, linenum, linent)
LDFILE *ldptr;
unsigned short linenum;
LINER linent;
Description
The function searches the line number entries of the common object file currently associated with ldptr. The function begins its search
with the line number entry for the beginning of a function and confines its search to the line numbers associated with a single function.
The function is identified by fcnindx, which is the index of its local symbols entry in the object file symbol table. The function reads
the entry with the smallest line number equal to or greater than linenum into linent.
The and functions provide the same behavior as After an initial call to or can be used to retrieve a series of line number entries associ-
ated with a single function. The function simply finds the line number entries for the function identified by fcnindx. The function finds
and reads the entry with the smallest line number equal to or greater than linenum into linent.
The functions and each return either success or failure. The function fails if one of the following occurs:
o If line number entries do not exist in the object file.
o If fcnindx does not index a function entry in the symbol table.
o If it does not find a line number equal to or greater than linenum.
The fails if it does not find a line number equal to or greater than linenum.

ldlseek(3) Library Functions Manual ldlseek(3)NAME
ldlseek, ldnlseek - seek to line number entries of a section of a common object file
SYNOPSIS
#include <stdio.h>
#include <filehdr.h>
#include <syms.h>
#include <ldfcn.h>
int ldlseek (ldptr, sectindx)
LDFILE *ldptr;
unsigned short sectindx;
int ldnlseek (ldptr, sectname)
LDFILE *ldptr;
char *sectname;
DESCRIPTION
ldlseek seeks to the line number entries of the section specified by sectindx of the common object file currently associated with ldptr.
ldnlseek seeks to the line number entries of the section specified by sectname.
ldlseek and ldnlseek return SUCCESS or FAILURE. NOTE: Line numbers are not associated with sections in the current implementation of the
symbol table; therefore, the second argument is ignored, but maintained for historical purposes.
If they cannot seek to the specified line number entries, both routines fail.
The program must be loaded with the object file access routine library
libmld.a.

Heres a script i wrote as a bit of practise. What it does is insert a line in the middle of a file. The line being $1 and the file being $2
#!/bin/bash
rm tempfile
touch tempfile
count=1
linenum= `wc -l < $2`
if
then
echo $1 >> $2
else
even=`expr "$linenum" % 2`
if
then... (3 Replies)
I have a huge file and every paragraph has a date. But I want to retrieve the paras for the last two days only. So I can grep and findout the linenum for the first line since yesterday. Now I want to display everything after that line. And I am trying to do this inside a script so the linenum is a... (4 Replies)
Hi there
How can I check line by line in a file?
I need to compare the first value with the second to know if they are equal. If those values are equal, I require to send "TRUE" to the output or "FALSE" otherwise until the complete file has been read.
Thank you (6 Replies)
im working a a perl script for a class and i need to call a file and print it out with line numbers.
i need help with this line with what to put in the capitalized words
