Memory is 69 * allocated in blocks, and as strings are added to the GStringChunk 70 * they are copied into the next free position in a block. When a block 71 * is full a new block is allocated. 72 * When storing a large number of strings, string chunks are more 73 * efficient than using g_strdup() since fewer calls to malloc() are 74 * needed, and less memory is wasted in memory allocation overheads. 75 * By adding strings with g_string_chunk_insert_const() it is also 76 * possible to remove duplicates. 77 * To create a new GStringChunk use g_string_chunk_new(). 78 * To add strings to a GStringChunk use g_string_chunk_insert(). 79 * To add strings to a GStringChunk, but without duplicating strings 80 * which are already in the GStringChunk, use 81 * g_string_chunk_insert_const(). 82 * To free the entire GStringChunk use g_string_chunk_free().
