puts, fputs - put a string on a stream SYNOPSIS
#include <stdio.h> int puts(const char *s); int fputs(const char *s, FILE *stream); DESCRIPTION
The puts() function writes the string pointed to by s, followed by a NEWLINE character, to the standard output stream stdout (see intro(3)). The terminating null byte is not written. The fputs() function writes the null-terminated string pointed to by s to the named output stream. The terminating null byte is not writ- ten. The st_ctime and st_mtime fields of the file will be marked for update between the successful execution of fputs() and the next successful completion of a call to fflush(3C) or fclose(3C) on the same stream or a call to exit(2) or abort(3C). RETURN VALUES
On successful completion, both functions return the number of bytes written; otherwise they return EOF and set errno to indicate the error. ERRORS
Refer to fputc(3C). USAGE
Unlike puts(), the fputs() function does not write a NEWLINE character at the end of the string. ATTRIBUTES

fputc, fputs, putc, putchar, puts - output of characters and strings SYNOPSIS
#include <stdio.h> int fputc(int c, FILE *stream); int fputs(const char *s, FILE *stream); int putc(int c, FILE *stream); int putchar(int c); int puts(const char *s); DESCRIPTION
fputc() writes the character c, cast to an unsigned char, to stream. fputs() writes the string s to stream, without its terminating null byte (''). putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once. putchar(c) is equivalent to putc(c, stdout). puts() writes the string s and a trailing newline to stdout. Calls to the functions described here can be mixed with each other and with calls to other output functions from the stdio library for the same output stream. For nonlocking counterparts, see unlocked_stdio(3). 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. ATTRIBUTES

It is not advisable to mix calls to output functions from the stdio library with low-level calls to write(2) for the file descriptor asso- ciated with the same output stream; the results will be undefined and very probably not what you want. SEE ALSO
