If you want to pass parameters from a shell to a program written in C, you can use the mechanism shown in the following piece of C code.
[code language=”c”]
#include <stdio.h>

* This program will simply list the arguments provided through the shell.
* argc: count of arguments from shell
* argv: parameters given through shell, given as strings seperated by blanks
int main(int argc, char *argv[]) {
int i;

printf("number of given arguments: %d", argc);

for(i=0; i < argc; i++) {
printf("\nparameter no %d: %s ", i, argv[i]);
