source: libcaca/trunk/cucul/cucul_internals.h @ 777

Last change on this file since 777 was 777, checked in by Sam Hocevar, 15 years ago
  • Replaced "struct cucul_*" and "struct caca_*" types with opaque typedefs such as cucul_dither_t instead of struct cucul_dither.
  • Made cucul_buffer_t an opaque structure and implemented the two getters cucul_get_buffer_data() and cucul_get_buffer_size().
  • Documented all missing functions and function parameters.
  • Property svn:keywords set to Id
