strtol() can be used to convert from string to binary, ANSCI C again.
For the case of vice versa, how are you going to store binary data types? C does not offer separate data type for this, so an...

>When i read 4 bytes from a socket the read function returns 0 value. what does it mean?
Read man pages on read(), the return value section. The return value of read() would be zero, stressing there...

Yes, see help on 'tail' command.

export EXINIT="se nu"
should do the trick. But if you do not want to type this after every login, include the same line in your startup script depending on your shell. Ex: .profile for KSH, .cshrc...

'set' is an internal command to most of the shells. You are tryin to spawn a new process with this, which is not allowed. This is why it is not working for you. On the other hand, 'ls' is an external...

That is because the last time you made a choice and hit [ENTER], the [ENTER] key was also stored in the input buffer along with your choice. And this [ENTER] key code was retrieved the next time you...

Yes, there is. See help on getenv()
char *p_home;
p_home = getenv("HOME");
/* Check for return value */

Yes you can. see if Pro*C/C++ Prescompiler has come along with your distribution of Oracle Client.

Or, here's a simpler way:
sprintf(final, "%.06d", num); /* 'num' is assumed to be of type int */
sprintf(final, "%.06d", atoi(num)); /* 'num' is assumed to be of type 'char *' */

'optarg' is of type 'string' (char *). If 'off_t' is of type int, use atoi() to convert optarg to type off_t.

Here's (http://users.actcom.co.il/~choo/lupg/tutorials/multi-thread/multi-thread.html) one.

If you are planning to read from the 'stdin' [Keyboard];
fgets(l_str, 255, stdin);

See man pages on 'crypt' command.

Yes, it is possible. See help on system()

You don't need to explicitly compile and then link the .c file. Instead, executing:

will first compile, then link, and the executable will be called filename.
Anyway, since you asked how you...

1.) Transfer each file, on file-by-file basis
2.) Transfer files in batches (mget 1* 2* 3*)

There's a limit to the number of fork() processes that can exist at any given point in time, and this limit is configurable. This threshold is there somewhere in the control panel (don't remember...

Here's one (http://www.google.com)

If you are looking for code:

#! /bin/ksh

tot_files=`ls -la | wc -l`

if [ $tot_files -ge 2 ]
then
echo " DIR not empty"
else
echo " DIR empty"
fi

man ls
man wc
ls -la | wc -l
This will include the "." and ".." directories too.

Try this:


#include <curses.h>

int main(void)
{
initscr();
clear();
refresh();
endwin();
}


And compile with:
cc prog.c -o prog -lcurses

There is no same header file under Linux, but you sure do have a similar library called the 'curses' library. You do have the getch() function in it as well. If you have installed it on your machin,...

What exactly are you asking for? Do you want to know how would reaf from the file or what? If so, it depends on the way the names have been stored in the file, if were written with fprintf(), use...

You can use the calculator provided by your flavort of UNIX, it's usually bc (dc). In AWK, it's bascically multiplying numbers like you would normally do (1.2 * 2.3).
