)

Description [src]

Retrieves the list of all available gain selectors as strings.

Available since: 0.8.27

Parameters

n_selectors

Type: guint*

Number of different gain selectors.

The argument will be set by the function.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: An array of utf8

A newly allocated array of strings, to be freed after use with g_free().

The length of the array is in the n_selectors argument.

The caller of the method takes ownership of the returned data container, but not the data inside it.

Each element is a NUL terminated UTF-8 string.
