  man pages->Tru64 Unix man pages -> biodone (9r)              



NAME    [Toc]    [Back]

       biodone - General: Indicates that block I/O is complete

SYNOPSIS    [Toc]    [Back]

       void biodone(
               struct buf *bp );

ARGUMENTS    [Toc]    [Back]

       Specifies  a  pointer  to a buf structure.  This structure
       contains information such as the binary status flags,  the
       major/minor device numbers, and the address of the associated
 buffer. This buffer is always a special buffer header
       owned exclusively by the device for handling I/O requests.

DESCRIPTION    [Toc]    [Back]

       The biodone routine is called after an  I/O  operation  to
       mark  the  buf structure as completed. It sets the b_flags
       member to B_SWAP, B_UBC, or B_ASYNC to indicate  the  type
       of  I/O operation that has completed. Other members may be
       set as well, depending on the type of I/O operation.

CAUTIONS    [Toc]    [Back]

       The routine panics if the buf structure is NULL.

RETURN VALUES    [Toc]    [Back]
