NAME
       pullupmsg - STREAMS: Concatenates bytes in a message

SYNOPSIS
       #include <sys/stream.h>

       int pullupmsg(
	       MBLKP message_block_ptr,
	       int len );

ARGUMENTS
       Specifies  a  pointer  to the message block whose associated data blocks are to be concatenated. The typedef MBLKP is an alternate name for
       typedef struct msgb *.  Specifies the number of bytes to concatenate.

DESCRIPTION
       The pullupmsg interface tries to combine multiple data blocks into a single block. The interface concatenates and aligns the first len data
       bytes  of  the  message	pointed  to by the message_block_ptr argument. If len equals the value -1, pullupmsg concatenates all data. If len
       bytes of the same message type cannot be found, pullupmsg fails and returns the value zero(0).

RETURN VALUES
       Upon successful completion, the pullupmsg interface returns the value 1. On failure, it returns the value zero(0).
