Usually it looks like this:
extern char *__progname;
'extern' means __progname must be available to external objects, so in
code with main():
#include <stdio.h>
char *__progname;
int main(int argc, char *argv[])
{
__progname = argv[0];
printf("%s\n", __progname);
return 0;
}
what you think? It works for me... so why basename(argv[0])?
