Output Program Example

This example consists of two parts: a script that is conﬁgured as the

output program, and a C program that must be compiled and installed as

/opt/sna/bin/catrje.

The script uses this program to produce sections of the offset that are

indexed by byte offsets from the PDIR ﬁle. The script is used to separate

the header and trailer from an output ﬁle and then to append the header

and trailer to each other section of output. Copies of these assembled

sections of output then print, according to the number of copies speciﬁed

in the PDIR.

Example:

/*Compile this program and install it as/opt/sna/bin/catrje*

#include <stdio.h>

void main(argc,argv)

int argc;

char *argv[];

{

int ch;

int count = 1;

int offset1,offset2;

offset1 = atoi(argv[1];

offset2 = atoi(argv[2];

ch = getc(stdin);

while ((ch != EOF) && (count <= offset2))

{

if (count >= offset1)

putc(ch,stdout);

ch = getc(stdin);

count++;

}

#!/bin/ksh

#This script is only an example. It is not supported code and

#Hewlett-Packard does not provide assistance if it does not work

#or needs modification.
