DESCRIPTION
The function fputs() writes the string pointed to by str to the stream pointed to by stream.
The function puts() writes the string str, and a terminating newline character, to the stream stdout.
RETURN VALUES
The fputs() function returns 0 on success and EOF on error; puts() returns a nonnegative integer on success and EOF on error.
ERRORS
[EBADF] The stream supplied is not a writable stream.
The functions fputs() and puts() may also fail and set errno for any of the errors specified for the routines write(2).
SEE ALSO ferror(3), putc(3), stdio(3)STANDARDS

FPUTS(3) BSD Library Functions Manual FPUTS(3)NAME
fputs, puts -- output a line to a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
int
fputs(const char *restrict s, FILE *restrict stream);
int
puts(const char *s);
DESCRIPTION
The function fputs() writes the string pointed to by s to the stream pointed to by stream.
The function puts() writes the string s, and a terminating newline character, to the stream stdout.
RETURN VALUES
The functions fputs() and puts() return a nonnegative integer on success and EOF on error.
ERRORS
[EBADF] The stream argument is not a writable stream.
The functions fputs() and puts() may also fail and set errno for any of the errors specified for the routines write(2).
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.
SEE ALSO ferror(3), fputws(3), putc(3), stdio(3)STANDARDS
The functions fputs() and puts() conform to ISO/IEC 9899:1990 (``ISO C90''). While not mentioned in the standard, both fputs() and puts()
print '(null)' if str is NULL.
