typedef Declarations

A typedef declaration creates a new name for an already existing type.
typedef unsigned char cc_t;
Read typedefs as variable declarations
typedef char ut_line_t[UT_LINESIZE];
Used for:
- Creating portable names for hardware quantities:
  typedef ___signed char      int8_t;
  typedef unsigned char    u_int8_t;
  typedef short             int16_t;
  typedef unsigned short  u_int16_t;
  typedef int               int32_t;
  typedef unsigned int    u_int32_t;
  typedef long              int64_t;
  typedef unsigned long   u_int64_t;
- Creating abstract names for known hardware representatrions:
  typedef u_int32_t in_addr_t;
  typedef u_int16_t in_port_t;
- Emulating C++/Java class definitions:
  typedef struct path path;
  struct path {
  /* [...] */
  }
