Ayke van Laethem 5c0a337c4f cgo: implement rudimentary C array decaying 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.		3 years ago
