puts—write a character string #include <stdio.h>
int puts(const char *s);
int _puts_r(struct _reent *reent, const char *s);
Description
puts writes the string at s (followed by a newline, instead of
the trailing null) to the standard output stream.
The alternate function _puts_r is a reentrant version. The extra
argument reent is a pointer to a reentrancy structure.
Returns
If successful, the result is a nonnegative integer; otherwise, the
result is EOF.
Portability
ANSI C requires puts, but does not specify that the result on
success must be 0; any non-negative value is permitted.
Supporting OS subroutines required: close, fstat, isatty,
lseek, read, sbrk, write.
