NAME

       vrb_write_min - write data from a VRB

LIBRARY

       -lvrb

SYNOPSIS

       #include <vrb.h>

       size_t vrb_write_min(vrb_p vrb, int fd, size_t maxsize, size_t minsize);

DESCRIPTION

       vrb_write_min  writes  a  minimum amount of data to a specified open file descriptor using
       write(2) from the specified virtual ring buffer until the  specified  maximum  length  has
       been written, the buffer is full, or an error is returned (including EAGAIN or EWOULDBLOCK
       for a non-blocking descriptor).  If there is insufficient data in the buffer to write  the
       minimum amount, then write(2) will not be called.

ARGUMENTS

       vrb_p vrb
       specifies which virtual ring buffer.

       int fd
       specifies the open file descriptor to write to

       size_t maxsize
       specifies the maximum length to write, or ~0 for unlimited.

       size_t minsize
       specifies the minimum length to write.

RETURN VALUE

       size_t
       If  successful,  the  actual  length  of data written from the buffer is returned.  If the
       minimum amount of data was not available to be written, 0 is returned.  If an error occurs
       from write(2), the return value is ~0 and errno is set by write(2).

ERRORS

       If an error is returned, then errno will have one of the following values:

       0      An  end-of-file  has  occurred.   Note that this is a different way of returning an
              end-of-file condition than write(2) uses.

       EINVAL An invalid virtual ring buffer pointer was specified.
