NAME
bp_copyout - copy from a driver buffer into a buf(9S) SYNOPSIS
#include <sys/types.h> #include <sys/buf.h> int bp_copyout(void *driverbuf, struct buf *bp, offset_t offset, size_t size); INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI). PARAMETERS
bp Pointer to the buffer header structure to copy to. driverbuf Driver buffer to copy from. offset Offset into bp where to start copying. size Size of copy. DESCRIPTION
The bp_copyout() function copies size bytes starting from the driver buffer driverbuf to offset bytes into the memory associated with bp. The offset only applies to bp. RETURN VALUES
Under normal conditions, 0 is returned to indicate a successful copy. Otherwise, -1 is returned if bp references invalid pages. CONTEXT
The bp_copyout() function can be called from user or kernel context only. SEE ALSO
