puts

Defined in header <stdio.h> 
int puts( const char* str );
+

Writes every character from the null-terminated string str and one additional newline character '\n' to the output stream stdout, as if by repeatedly executing fputc.

+

The terminating null character from str is not written.

+

Parameters

+ +
str - character string to be written

Return value

On success, returns a non-negative value.

+

On failure, returns EOF and sets the error indicator (see ferror()) on stream.

+

Notes

The puts function appends the newline character to the output, while fputs function does not.

+

Different implementations return different non-negative numbers: some return the last character written, some return the number of characters written (or INT_MAX if the string was longer than that), some simply return a non-negative constant.

+

A typical cause of failure for puts is running out of space on the file system, when stdout is redirected to a file.

+

Example

#include <stdio.h>
+ 
+int main(void)
+{
+    int rc = puts("Hello World");
+ 
+    if (rc == EOF)
+        perror("puts()"); // POSIX requires that errno is set
+}

Output:

+
Hello World
