Re: [PATCH v3 0/1] MR8296: msi/tests: Fix wrong character count for RegSetValueExA.

[Hans Leidekker (＠hans)]

Let's make it a real function and call it reg_set_str():
```
LONG reg_set_str( HKEY key, const char *subkey, const char *value )
{
    return RegSetValueExA( key, subkey, 0, REG_SZ, (const BYTE *)value, strlen(value) + 1 );
}
```

This way we get type checking on the value parameter and allow use with variable strings as well.
