setenv.

helllo every body ..
hope you are having good time programming in unix .

here is a little problem faced me :

Code:

setenv("myvar","bla bla",1); 
system("myvar=$(grep....)); 

printf("%s\n", getenv("myvar"));

will print :
bla bla ..

how can i get the value of grep into my program ?
what i figurd out that is after

Code:

system("myvar=hello");

myvar will have the same old value,
but:

Code:

system("myvar=hello; echo $myvar");

will pring hello without changing myvar value.
