NAME
     freemsg - free all message blocks in a message

SYNOPSIS
     #include 



     void freemsg(mblk_t *mp);


INTERFACE LEVEL
     Architecture independent level 1 (DDI/DKI).

PARAMETERS
     mp    Pointer to  the  message  blocks  to  be  deallocated.
           mblk_t is an instance of the msgb(9S) structure. If mp
           is NULL, freemsg() immediately returns.


DESCRIPTION
     The freemsg() function calls freeb(9F) to free  all  message
     and  data  blocks  associated with the message pointed to by
     mp.

CONTEXT
     The freemsg() function can be called from  user,  interrupt,
     or kernel context.

NOTES
     The behavior of freemsg() when  passed  a  NULL  pointer  is
     Solaris-specific.
