Declaration
gboolean
g_key_file_has_key (
GKeyFile* key_file,
const gchar* group_name,
const gchar* key,
GError** error
)
Description
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
or not a key exists.
Available since: 2.6
This method is not directly available to language bindings.
