QNX SDP8.0C Library ReferenceAPIDeveloper
Write a string to stdout
Synopsis:
#include <stdio.h>
int puts( const char *buf );
Arguments:

- A pointer to the zero-terminated string that you want to write.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The puts() function writes the character string pointed to by buf to the stdout stream, and appends a newline character to the output. The terminating NUL character of buf isn't written.
Returns:
A nonnegative value for success, or EOF if an error occurs (errno is set).
Examples:
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
FILE *fp;
char buffer[80];
fp = freopen( "file", "r", stdin );
while( gets( buffer ) != NULL ) {
puts( buffer );
}
fclose( fp );
return EXIT_SUCCESS;
}
