It is useful to be able to run a main() function only when a program is run directly. This is a central feature in programming scripts; the feature is called /scripted main/.
C
C programs have scripted main by default; as long as main() is not included in the header file, this program's (empty) API is accessible by other C code.
<lang c>#include "scriptedmain.h"
- include <stdio.h>
- include <unistd.h>
int main(int argc, char **argv) { char cwd[1024]; getcwd(cwd, sizeof(cwd));
printf("Directory: %s\n", cwd);
printf("Program: %s\n", argv[0]);
printf("Number of Args: %d\n", argc);
int i; for (i = 0; i < argc; i++) { printf("Arg: %s\n", argv[i]); }
return 0; }</lang>
