# nerr\_match(3)

walk the NEOERR chain for a matching error (clearsilver)

## 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.
