# sasl\_getopt\_t(3)

The SASL get option callback

## NAME

sasl\_getopt\_t - The SASL get option callback

## SYNOPSIS

```
#include <sasl/sasl.h>

int sasl_getopt_t(void *context,
		     const char *plugin_name,
		     const char *option,
		     const char ** result,
		     unsigned * len);
```

## DESCRIPTION

**sasl\_getopt\_t** is used to retrieve an option, often mechanism specific, from the application. An example of this is requested what KERBEROS\_V4 srvtab file to use. *plugin\_name* is the plugin this value if for. *option* is a string representing the option. A common option that all server applications should handle is  method for checking plaintext passwords. See the administrators guide for a full description of this option.

Memory management of options supplied by the getopt callback should be done by the application, however, any requested option must remain available until the callback is no longer valid.  That is, when sasl\_dispose is called for a the connection it is associated with, or sasl\_done is called for global callbacks.

## RETURN VALUE

SASL callback functions should return SASL return codes. See sasl.h for a complete list. SASL\_OK indicates success.
