       freerbuf(D3)                                            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.
