NAME
       adjmsg - STREAMS: Removes the specified number of bytes from a message

SYNOPSIS
       #include <sys/stream.h>

       int adjmsg(
	       MBLKP message_ptr,
	       int len_to_trim );

ARGUMENTS
       Specifies  a pointer to the message that you want adjmsg to trim.  Specifies the number of bytes that you want adjmsg to remove (trim) from
       the message.

DESCRIPTION
       The adjmsg interface removes a specified number of bytes from a message. The absolute value of the len_to_trim argument specifies how  many
       bytes  that  adjmsg  removes.  If the number of bytes passed to len_to_trim is greater than 0 (zero), adjmsg removes bytes from the head of
       the message. If the number of bytes passed to len_to_trim is less than 0 (zero), adjmsg removes bytes from the tail of the message.

       The adjmsg interface fails if the value you pass to the len_to_trim argument is greater than the number of  bytes  stored  in  the  message
       pointer argument, message_ptr.

RETURN VALUES
       If the adjmsg interface successfully trims the message, it returns the value 1. Otherwise, it returns the value 0 (zero).
