func nmbpaddr 

Returns the address corresponding to the indicated NM breakpoint index.

Syntax 

       %nmbpaddr (bpindex [pin])

This function accepts an index for an existing NM breakpoint and returns
the address where the breakpoint is located.  The default action is to
look for breakpoints set by the current PIN. Breakpoint addresses for
other PINs (including the global PIN) may be retrieved by using the
optional pin parameter.

Formal Declaration 

     nmbpaddr:lptr (bpindex:u32 [pin:s16=0])

Parameters 

 bpindex         The index of the breakpoint whose address is to be
                 returned.

 pin             Look for breakpoints set by this PIN. Default is the
                 caller's PIN (a pin of 0 implies this).  To specify
                 system (global) breakpoints, use a -1 (or 32762) as the
                 PIN.

Examples 

     $nmdebug > bl 
     NM      [1] PROG $ c3.56d80   test_screen+$ab3
     NM      [2] PROG $ c3.4cf18   test_file^
     NM     @[1] SYS  $ a.004b9130 FOPEN

First, list the existing breakpoints.

     $nmdebug > wl nmbpaddr(1) 
     PROG $c3.56d80

     $nmdebug > l nmbpaddr(1, -1) 
     SYS $a.4b9130

Now use the function to return the address associated with process local
breakpoint number one and then with system breakpoint number one.
