rmvb - STREAMS: Removes a message block from a message
MBLKP message_to_be_removed );
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 *.
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
Upon successful completion, rmvb returns a pointer to the
message block (minus the removed message block). The
pointer is NULL if the message_to_be_removed argument was
the only message block before the call to the rmvb interface.
If the message block passed to message_to_be_removed
does not exist, rmvb returns the value -1.
