GLib KeyFilehas_key

gboolean
g_key_file_has_key(
GKeyFile*key_file,
constgchar*group_name,
constgchar*key,
GError**error
)

Looks whether the key file has the key key in the group group_name.

Note that this function does not follow the rules for GError strictly; the return value both carries meaning and signals an error. To use this function, you must pass a GError pointer in error, and check whether it is not NULL to see if an error occurred.

Language bindings should use g_key_file_get_value() to test whether a key exists.

Available since: 2.6

This method is not directly available to language bindings.

group_name

Type: const gchar*

A group name.

The data is owned by the caller of the method.

The value is a NUL terminated UTF-8 string.

key

Type: const gchar*

A key name.

The data is owned by the caller of the method.

The value is a NUL terminated UTF-8 string.

error

Type:

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.
