pullupmsg(9r)
NAME
  pullupmsg - STREAMS: Concatenates bytes in a message

SYNOPSIS
  #include <sys/stream.h>

  int pullupmsg(
	  MBLKP message_block_ptr,
	  int len );

ARGUMENTS
  message_block_ptr
      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 *.

  len 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).
