How to use _fputc_nolock() to write characters to stdout without locking in C

Answer 1

#include <stdio.h>

int main(void)
{
	char str[] = "C Programming\n";
	char* p;

	p = str;
	
	// int _fputc_nolock(int c, FILE* stream);
	// _fputc_nolock - not protected from interference by other threads

	while ((*p != '\0') && _fputc_nolock(*(p++), stdout) != EOF);

	return 0;
}
