DESCRIPTION
     The sysdecode_utrace() function outputs a textual representation of a
     utrace(2) record identified by buf and len to the output stream fp.

     The function only outputs a representation for certain types of records.
     If a record is recognized, the function outputs the description and
     returns a non-zero value.  If the record is not recognized, the function
     does not output anything and returns zero.  The sysdecode_utrace()
     function currently recognizes utrace(2) records generated by malloc(3)
     and rtld(1).

RETURN VALUES
     The sysdecode_utrace() function returns a non-zero value if it recognizes
     a utrace(2) record; otherwise it returns zero.
