But you can use the `data` field, with some casting, and using the `len` field to avoid going over the array bounds. > gsl_fft_radix2_transform ( (double*) g_array_data, 1, 256); The code below would look like: gsl_fft_radix2_transform ((double *) g_array_data->data, 1, 256); But remember: operating on the underlying C array wrapped by a GArray can be tricky because GArray grows and shrinks as needed. You should never exceed the length of the GArray, and the code you're calling should not try to modify the array data pointer itself (e.g. by reallocating it).
