Argument to wlcl_dblbuf_t::callback.

data_ptr

void* _wlcl_dblbuf_t::data_ptr

Blob of memory-mapped buffer data.

data_size

size_t _wlcl_dblbuf_t::data_size

Size of wlcl_dblbuf_t::data_ptr.

frame_is_due

bool _wlcl_dblbuf_t::frame_is_due

Indicates that a frame is due to be drawn.

height

unsigned _wlcl_dblbuf_t::height

Height of the buffer, in pixels.

released

int _wlcl_dblbuf_t::released

Number of items in wlcl_dblbuf_t::released_buffer_ptrs.

released_buffer_ptrs
