如何处理c中的错误返回

typedef enum {
    SUCCESS = 0,
    ERROR_NULL_POINTER,
    ERROR_INVALID_ARGUMENT,
    ERROR_OUT_OF_MEMORY,
    ERROR_FILE_NOT_FOUND,
    ERROR_NETWORK_FAILURE,
    // ...
} ErrorCode;

const char* get_error_message(ErrorCode code) {
    switch (code) {
        case SUCCESS:
            return "Success";
        case ERROR_NULL_POINTER:
            return "Null pointer error";
        case ERROR_INVALID_ARGUMENT:
            return "Invalid argument error";
        case ERROR_OUT_OF_MEMORY:
            return "Out of memory error";
        case ERROR_FILE_NOT_FOUND:
            return "File not found error";
        case ERROR_NETWORK_FAILURE:
            return "Network failure error";
        // ...
    }
}

#define CHECK_ERROR(expr) \
    do { \
        ErrorCode code = (expr); \
        if (code != SUCCESS) { \
            printf("Error: %s\n", get_error_message(code)); \
            goto error; \
        } \
    } while (0)

void handle_error(ErrorCode code, const char* message) {
    printf("Error: %s (code=%d)\n", message, code);
    exit(1);
}
