NAME

       geterror - return I/O error

SYNOPSIS

       #include <sys/types.h>
       #include <sys/buf.h>
       #include <sys/ddi.h>

       int geterror(struct buf *bp);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       bp	Pointer to a buf(9S) structure.

DESCRIPTION

       geterror() returns the error number  from the error field of the  buffer header structure.

RETURN VALUES

       An error number indicating the error condition of the I/O request is  returned. If the I/O request completes successfully,  0 is returned.

CONTEXT

       geterror() can be called from user or interrupt context.

NAME

       bioerror - indicate error in buffer header

SYNOPSIS

       #include <sys/types.h>
       #include <sys/buf.h>
       #include <sys/ddi.h>

       void bioerror(struct buf *bp, int error);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI)

PARAMETERS

       bp	Pointer to the buf(9S) structure describing the transfer.

       error	Error number to be set, or zero to clear an error indication.

DESCRIPTION

       If  error  is  non-zero,  bioerror() indicates an error has occured in the buf(9S) structure. A subsequent call to geterror(9F) will return
       error.

       If error is  0, the error indication is cleared and a subsequent call to geterror(9F) will return  0.

CONTEXT

       bioerror() can be called from any context.
