puts, fputs - Writes a string to a stream
const char *string );
const char *string,
FILE *stream );
Standard C Library (libc)
Points to a string to be written to output.
Points to the FILE structure of an open file.
The puts() function writes the null-terminated string pointed to by the
string parameter, followed by a newline character, to the standard output
The fputs() function writes the null-terminated string pointed to by the
string parameter to the output stream specified by the stream parameter.
The fputs() function does not append a newline character.
Neither function writes the terminating null byte.
The st_ctime and st_mtime fields of the file are marked for update between
the successful execution of the puts() or fputs() function and the next
successful completion of a call to one of the following:
· An fflush() or fclose() function on the same stream
· The exit() or abort() function
AES Support Level:
Upon successful completion, the puts() and fputs() functions return the
number of characters written. Both subroutines return EOF on an error.
The puts() and fputs() functions fail under either of the following
· The stream is unbuffered.
· The stream's buffer needed to be flushed, the function call caused an
underlying write() or lseek() to be invoked, and this underlying
operation fails with incomplete output.
In addition, if any of the following conditions occur, the puts() or
fputs() function sets errno to the corresponding value.
The O_NONBLOCK option is set for the file descriptor underlying stream
and the process would be delayed in the write operation.
The file descriptor underlying stream is not a valid file descriptor
open for writing.
An attempt was made to write to a file that exceeds the process's file
size limit or the maximum file size.
The read operation was interrupted by a signal that was caught, and no
data was transferred.
The implementation supports job control; the process is a member of a
background process group attempting to write to its controlling
terminal; TOSTOP is set; the process is neither ignoring nor blocking
SIGTTOU, and the process group of the process is orphaned. This error
may also be returned under implementation-defined conditions.
There was no free space remaining on the device containing the file.
An attempt was made to write to a pipe or FIFO that is not open for
reading by any process. A SIGPIPE signal will also be sent to the
Functions: fgetws(3), fputws(3), gets(3), printf(3), putc(3), putwc(3).
