NAME

       buffer_puts - write ASCIIZ string to buffer

SYNTAX

       #include <buffer.h>

       int buffer_puts(buffer* b,const char* x);

DESCRIPTION

       buffer_puts is like buffer_put with len determined as the number of bytes before the first  in x.

       The  difference	to buffer_putsalign is that, when there isn't enough space for new data, buffer_puts calls buffer_flush before copying any
       data, while buffer_putsalign fills all available space with data before calling buffer_flush.

RETURN VALUE

       buffer_puts returns 0 if everything was fine, -1 on error (setting errno).

io_pipe(3)						     Library Functions Manual							io_pipe(3)

NAME

       io_pipe - create a Unix pipe

SYNTAX

       #include <io.h>

       int io_pipe(int64 pfd[2]);

DESCRIPTION

       io_pipe	creates  a  new UNIX ``pipe.'' The pipe can receive data and provide data; any bytes written to the pipe can then be read from the
       pipe in the same order.

       A pipe is typically stored in an 8192-byte memory buffer; the exact number depends on the UNIX kernel. Bytes are written to the end of  the
       buffer  and  read  from	the beginning of the buffer. Once a byte has been read, it is eliminated from the buffer, making space for another
       byte to be written; readers cannot ``rewind'' a pipe to read old data. Once 8192 bytes have been written to the buffer, the pipe  will  not
       be  ready for further writing until some of the bytes have been read. Once all the bytes written have been read, the pipe will not be ready
       for further reading until more bytes are written.

       io_pipe sets d[0] to the number of a new descriptor reading from the pipe, and sets d[1] to the number of a new descriptor writing  to  the
       pipe.  It then returns 1 to indicate success. If something goes wrong, io_pipe returns 0, setting errno to indicate the error; in this case
       it frees any memory that it allocated for the new pipe, and it leaves d alone.
