Whoa. Total botch there. I thought you were using threads for some reason. Sorry.
The variable doesn't carry across seperate processes because they don't share that memory; to get shared memory we have to explicitly create some. Like so:

hi all,
my requirement is to create a thread by calling another function.
i.e i dont call pthread_create directly from main, but by calling another function (createThd - below ), from main.
Example:

I think I know the answer but I'll ask and see if someone with more expertise can share new light on this topic: Does Ksh have the capability to create new threads (not processes) and/or offer some multiplexing on named pipes?
Thanks for your assistance!

mem
MEM(4) Linux Programmer's Manual MEM(4)NAME
mem, kmem, port - system memory, kernel memory and system ports
DESCRIPTION
mem is a character device file that is an image of the main memory of the computer. It may be used, for example, to examine (and even
patch) the system.
Byte addresses in mem are interpreted as physical memory addresses. References to nonexistent locations cause errors to be returned.
Examining and patching is likely to lead to unexpected results when read-only or write-only bits are present.
It is typically created by:
mknod -m 660 /dev/mem c 1 1
chown root:kmem /dev/mem
The file kmem is the same as mem, except that the kernel virtual memory rather than physical memory is accessed.
It is typically created by:
mknod -m 640 /dev/kmem c 1 2
chown root:kmem /dev/kmem
port is similar to mem, but the I/O ports are accessed.
It is typically created by:
mknod -m 660 /dev/port c 1 4
chown root:mem /dev/port
FILES
/dev/mem
/dev/kmem
/dev/port
