NAME
       rmvb - STREAMS: Removes a message block from a message block

SYNOPSIS
       #include <sys/stream.h>

       MBLKP rmvb(
	       MBLKP message_block_ptr,
	       MBLKP message_to_be_removed );

ARGUMENTS
       Specifies  a pointer to the message block from which a message block is
       to be removed. The typedef MBLKP	 is  an	 alternate  name  for  typedef
       struct msgb *.  Specifies a pointer to the message block to be removed.
       The typedef MBLKP is an alternate name for typedef struct msgb *.

DESCRIPTION
       The rmvb interface removes a message block  (the	 message_to_be_removed
       argument)  from	a  message  block (the message_block_ptr argument) and
       returns a pointer to the altered message block. The rmvb interface does
       not  free the message block; it merely removes the message block. It is
       the module's or driver's responsibility to free the message block.

RETURN VALUES
       Upon successful completion, rmvb returns a pointer to the message block
       (minus  the  removed  message  block).  The pointer is NULL if the mes‐
       sage_to_be_removed argument was the only message block before the  call
       to   the	  rmvb	 interface.  If	 the  message  block  passed  to  mes‐
       sage_to_be_removed does not exist, rmvb returns the value -1.
