wl_array(3) Wayland wl_array(3) NAME wl_array SYNOPSIS #include Public Member Functions void wl_array_init (struct wl_array *array) void wl_array_release (struct wl_array *array) void * wl_array_add (struct wl_array *array, size_t size) int wl_array_copy (struct wl_array *array, struct wl_array *source) Data Fields size_t size size_t alloc void * data Related Functions (Note that these are not member functions.) #define wl_array_for_each(pos, array) Detailed Description Dynamic array A wl_array is a dynamic array that can only grow until released. It is intended for relatively small allocations whose size is variable or not known in advance. While construction of a wl_array does not require all elements to be of the same size, wl_array_for_each() does require all elements to have the same type and size. Member Function Documentation void * wl_array_add (struct wl_array * array, size_t size) Increases the size of the array by size bytes. Parameters array Array whose size is to be increased size Number of bytes to increase the size of the array by Returns A pointer to the beginning of the newly appended space, or NULL when resizing fails. int wl_array_copy (struct wl_array * array, struct wl_array * source) Copies the contents of source to array. Parameters array Destination array to copy to source Source array to copy from Returns 0 on success, or -1 on failure void wl_array_init (struct wl_array * array) Initializes the array. Parameters array Array to initialize void wl_array_release (struct wl_array * array) Releases the array data. Note Leaves the array in an invalid state. Parameters array Array whose data is to be released Friends And Related Function Documentation #define wl_array_for_each(pos, array) [related] Value:.PP for (pos = (array)->data; \ (const char *) pos < ((const char *) (array)->data + (array)->size); \ (pos)++) Iterates over an array. This macro expresses a for-each iterator for wl_array. It assigns each element in the array to pos, which can then be referenced in a trailing code block. pos must be a pointer to the array element type, and all array elements must be of the same type and size. Parameters pos Cursor that each array element will be assigned to array Array to iterate over See also wl_list_for_each() Field Documentation size_t wl_array::alloc Allocated space void* wl_array::data Array data size_t wl_array::size Array size Author Generated automatically by Doxygen for Wayland from the source code.
