Example of snprintf

#include <stdio.h>

int main(int argc, const char *argv[]) {
	int count;
	int i;
	char buf[10];

	for (i = 0; i < 10; i++)
		buf[i] = 1;

	count = snprintf(buf, 10, "%s", "abc");

	printf("count: %d, string: %s\n", count, buf);

	for (i = 0; i < 10; i++)
		printf("buf[%d]: %d\n", i, buf[i]);

	return 0;
}
