This is just a first step. It's not complete, but it gets some real
world C code to parse.
This signature, from the ESP-IDF:
esp_err_t esp_wifi_get_mac(wifi_interface_t ifx, uint8_t mac[6]);
Was previously converted to something like this (pseudocode):
C.esp_err_t esp_wifi_get_mac(ifx C.wifi_interface_t, mac [6]uint8)
But this is not correct. C array parameters will decay. The array is
passed by reference instead of by value. Instead, this would be the
correct signature:
C.esp_err_t esp_wifi_get_mac(ifx C.wifi_interface_t, mac *uint8)
So that it can be called like this (using CGo):
var mac [6]byte
errCode := C.esp_wifi_get_mac(C.ESP_IF_WIFI_AP, &mac[0])
This stores the result in the 6-element array mac.
