Shamrock, sorry about not providing proper details previously.
Program A does have main() fn separately. Program A and B are completely two different programs, just that Program B is called through execl() in Program A.
Following are additional details on Program A.
PROGRAM A
Code:
int
main(int argc, char *argv[])
{
// This program accepts several customized options through socket.
// The option/module I am writing is called SearchFiles
// This program does not exit until another option Terminate is called through client socket
// Meaning, SearchFiles option can be called more than once
// SearchFiles does operation nothing to do with pipes. it does a customized path translation.
// The data that it passes to StartPipe() method is only the socket and the path in a char array as below:
sockinetbuf s;
string socket_data;
s >> socket_data;
while(s)
{
s >> socket_data;
if (socket_data == "SearchFiles")
{
char input_to_program_b[1000] = "blah blah blah";
StartPipe(s, input_to_program_b);
}
else if (socket_data == "Terminate")
{
exit(0);
}
}
}
Function StartPipe() is as given in the first post.
Hi,
Program A: uses pipe()
I am able to read the stdout of PROGAM B (stdout got through system() command) into PROGRAM A using:
* child
-> dup2(fd, STDOUT_FILENO);
-> execl("/path/PROGRAM B", "PROGRAM B", NULL);
* parent
-> char line;
-> read(fd, line, 100);

Hello,
I have a script that monitors files uploaded via ftp. After a successful upload, the file name is written to the pipe.
There is another program that reads this pipe and allows automatically run any program or script ( say test.sh ) to process the newly uploaded file.
cat test.sh... (2 Replies)

spell - GNU spell, a Unix spell emulator
SYNOPSIS

DESCRIPTION
This manual page documents briefly the spell command. This manual page was written for the Debian GNU/Linux distribution (but may be used
by others), because the original program does not have a manual page. Instead, it has documentation in the GNU Info format; see below.
spell is a program that emulates the traditional Unix spell command by calling the Ispell utility.
It is a spell checking program which prints each misspelled word on a line of its own.
OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options are included
below. For a complete description, see the Info files.
-I, --ispell-version
Print Ispell's version.
-V, --version
Print the version number.
-b, --british
Use the British dictionary.
-d, --dictionary=FILE
Use FILE to look up words.
-h, --help
Print a summary of the options.
-i, --ispell=PROGRAM
Calls PROGRAM as Ispell.
-D, --ispell-dictionary=DICTIONARY
Use the named DICTIONARY to look up words.
-l, --all-chains
Ignored; for compatibility.
-n, --number
Print line numbers before lines.
-o, --print-file-name
