(Sorry for confusing: I should have written:) Please see below for specifications on fputs() Linux: RETURN VALUE fputc(), putc() and putchar() return the character written as an unsigned char cast to an int or EOF on error. puts() and fputs() return a nonnegative number on success, or EOF on error. Mac OS: COMPATIBILITY fputs() now returns a non-negative number (as opposed to 0) on successful completion. As a result, many tests (e.g., "fputs() == 0", "fputs() != 0") do not give the desired result. Use "fputs() != EOF" or "fputs() == EOF" to determine success or failure. Posix: RETURN VALUE Upon successful completion, fputs() shall return a non-negative number. Otherwise, it shall return EOF, set an error indicator for the stream, and set errno to indicate the error. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
