bufferin(3f) — CX/UX 6.20



bufferio(3F)                                         bufferio(3F)



NAME
     bufferin, bufferout, status - perform VOS-like asynchronous
     I/O

SYNOPSIS
     subroutine bufferin (lunit,buffer,count,stat,n)
     subroutine bufferout (lunit,buffer,count,stat,n)
     subroutine status (lunit)
     integer buffer(*), count, stat

DESCRIPTION
     These routines mimic the VOS-like asynchronous I/O functions
     BUFFERIN, BUFFEROUT, and STATUS.

     lunit must refer to an open logical unit.  buffer is an
     integer variable or array containing the data to be read or
     written.  count is the number of bytes to be transferred
     (and must be a multiple of 4).  stat will be set to opera-
     tion status when

           call status(lunit)

     is issued on the same logical unit number.  Values include:

       <0   an error occurred
       2    successful completion of I/O
       3    End of File encountered on a bufferin operation
       4    End of Tape (or disk full) on a bufferout operation

     n is the number of bytes actually transferred.

     The variables buffer, count, and stat must be declared VOLA-
     TILE.

FILES
     /usr/lib/libI77.a

NOTES
     When compiling source with the -Qocs option, an explicit
     underscore needs to be added to the end of the routine name.
