This noncompliant code example includes a helper() function that is implicitly declared to have external linkage.
| Code Block | ||||
|---|---|---|---|---|

enum { MAX = 100 };
int helper(int i) {
/* perform some computation based on i */
}
int main(void) {
size_t i;
int out[MAX];
for (i = 0; i < MAX; i++) {
out[i] = helper(i);
}
/* ... */
}

This compliant solution declares helper() to have internal linkage, thereby preventing external functions from using it.
| Code Block | ||||
|---|---|---|---|---|
| ||||
enum {MAX = 100};
static int helper(int i) {
/* perform some computation based on i */
}
int main(void) {
size_t i;
int out[MAX];
for (i = 0; i < MAX; i++) {
out[i] = helper(i);
}
/* ... */
}
