GIFunctionInfo represents a function, method or constructor.
To find out what kind of entity a GIFunctionInfo represents, call
g_function_info_get_flags().
See also GICallableInfo for information on how to retreive arguments and other metadata.
GIFunctionInfoFlags
g_function_info_get_flags (GIFunctionInfo *info);
Obtain the GIFunctionInfoFlags for the info
.
GIPropertyInfo *
g_function_info_get_property (GIFunctionInfo *info);
Obtain the property associated with this GIFunctionInfo.
Only GIFunctionInfo with the flag GI_FUNCTION_IS_GETTER or
GI_FUNCTION_IS_SETTER have a property set. For other cases,
NULL will be returned.
the property or NULL if not set. Free it with
g_base_info_unref() when done.

const gchar *
g_function_info_get_symbol (GIFunctionInfo *info);
Obtain the symbol of the function. The symbol is the name of the
exported function, suitable to be used as an argument to
g_module_symbol().
GIVFuncInfo *
g_function_info_get_vfunc (GIFunctionInfo *info);
Obtain the virtual function associated with this GIFunctionInfo.
Only GIFunctionInfo with the flag GI_FUNCTION_WRAPS_VFUNC has
a virtual function set. For other cases, NULL will be returned.
the virtual function or NULL if not set.
Free it by calling g_base_info_unref() when done.

gboolean g_function_info_invoke (GIFunctionInfo *info,const GIArgument *in_args,int n_in_args,const GIArgument *out_args,int n_out_args,GIArgument *return_value,GError **error);
Invokes the function described in info
with the given
arguments. Note that inout parameters must appear in both
argument lists. This function uses dlsym() to obtain a pointer
to the function, so the library or shared object containing the
described function must either be linked to the caller, or must
have been g_module_symbol()ed before calling this function.
