Here is a quicky c program:
Code:
#include <stdio.h>

int main(argc, argv)
int argc;
char *argv[];
{
        int i,k;
        printf("argc = %d \n", argc);
        for(i=0; argv[i]; i++) {
                printf("parameter = %d \n", i);
                for(k=0; argv[i][k]; k++)
                        printf("   char = %c \n", argv[i][k]);
        }
        exit(0);
}

I can modify it into:
Code:
#include <stdio.h>

main()
{

char *argv2[20];
int argc2;
int ret;

argv2[0] = "not_main function";
argv2[1] = "arg one";
argv2[2] = "222";
argv2[3] = NULL;
argc2 = 3;
ret = not_main(argc2, argv2);

/* if not_main uses exit(), we will never get here */
exit(0);

}


int not_main(argc, argv)
int argc;
char *argv[];
{
        int i,k;
        printf("argc = %d \n", argc);
        for(i=0; argv[i]; i++) {
                printf("parameter = %d \n", i);
                for(k=0; argv[i][k]; k++)
                        printf("   char = %c \n", argv[i][k]);
        }
        exit(0);
}
