ddriver

Structure of the driver object in Depressure:

typedef struct ddriver {
  u32 pattern; // DDRV
  u32 version; // For example 0x00010000u is 1.0.0
  u64 next; // Filled by kernel, contains address of next `ddriver` structure in Virtual Memory, 0 = End
  u64 type; // Type of driver (See: Variables>DDRIVER_TYPE_*)
  char name[32]; // Name of driver (ASCII, Null-term)
  u64 entry; // Filled by kernel, entry point of driver in Virtual Memory
  u64 api; // Filled by driver, API of driver (See also: Writing my first driver)
  u64 data; // Driver private data
} ddriver_t
