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.
