freerbuf(D3)

NAME
     freerbuf - free a raw buffer header

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

     void freerbuf(buf_t *bp);


   Arguments
     bp        Pointer to a previously allocated buffer header structure.

DESCRIPTION
     freerbuf frees a raw buffer header previously allocated by getrbuf(D3).

   Return Values
     None

USAGE
     freerbuf may not be used on a buffer header obtained through an interface
     other than getrbuf.

     freerbuf is typically called from a driver's biodone (D3) routine, as
     specified in the b_iodone field of the buf(D4) structure.

   Level
     Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

     Driver-defined basic locks, read/write locks, and sleep locks may be held
     across calls to this function.
