NAME

       nerr_match - walk the NEOERR chain for a matching error (clearsilver)

SYNOPSIS

       #include <util/neo_err.h>

       int nerr_match (NEOERR *err, NERR_TYPE type);

ARGUMENTS

       err - the NEOERR that has an error.
       type - the NEOERR type, as registered with nerr_register

DESCRIPTION

       nerr_match  is  used  to  walk  the  NEOERR  chain and match the error against a specific error type.  In
       exception parlance, this would be the equivalent of "catch".  Typically, you can just  compare  a  NEOERR
       against STATUS_OK or just test for true if you are checking for any error.
