.Ss
int nerr_match (NEOERR *err, NERR_TYPE type);

.Se

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

.SH 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.
