As a result, it 20 | will not produce a .lib file when it is built. If you wish this project 21 | to be a project dependency of some other project, you will either need to 22 | add code to export some symbols from the DLL so that an export library 23 | will be produced, or you can check the "doesn't produce lib" checkbox in 24 | the Linker settings page for this project. 25 | 26 | /////////////////////////////////////////////////////////////////////////////

It may introduce some 206 | output latency (reading input without producing any output) except when 207 | forced to flush. 208 | 209 | The detailed semantics are as follows. deflate performs one or both of the 210 | following actions: 211 | 212 | - Compress more input starting at next_in and update next_in and avail_in 213 | accordingly. If not all input can be processed (because there is not 214 | enough room in the output buffer), next_in and avail_in are updated and 215 | processing will resume at this point for the next call of deflate(). 216 | 217 | - Provide more output starting at next_out and update next_out and avail_out 218 | accordingly. This action is forced if the parameter flush is non zero. 219 | Forcing flush frequently degrades the compression ratio, so this parameter 220 | should be set only when necessary (in interactive applications). 221 | Some output may be provided even if flush is not set. 222 | 223 | Before the call of deflate(), the application should ensure that at least 224 | one of the actions is possible, by providing more input and/or consuming 225 | more output, and updating avail_in or avail_out accordingly; avail_out 226 | should never be zero before the call. The application can consume the 227 | compressed output when it wants, for example when the output buffer is full 228 | (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK 229 | and with zero avail_out, it must be called again after making room in the 230 | output buffer because there might be more output pending. 231 | 232 | If the parameter flush is set to Z_SYNC_FLUSH, all pending output is 233 | flushed to the output buffer and the output is aligned on a byte boundary, so 234 | that the decompressor can get all input data available so far. (In particular 235 | avail_in is zero after the call if enough output space has been provided 236 | before the call.) Flushing may degrade compression for some compression 237 | algorithms and so it should be used only when necessary. 238 | 239 | If flush is set to Z_FULL_FLUSH, all output is flushed as with 240 | Z_SYNC_FLUSH, and the compression state is reset so that decompression can 241 | restart from this point if previous compressed data has been damaged or if 242 | random access is desired. Using Z_FULL_FLUSH too often can seriously degrade 243 | the compression. 244 | 245 | If deflate returns with avail_out == 0, this function must be called again 246 | with the same value of the flush parameter and more output space (updated 247 | avail_out), until the flush is complete (deflate returns with non-zero 248 | avail_out). 249 | 250 | If the parameter flush is set to Z_FINISH, pending input is processed, 251 | pending output is flushed and deflate returns with Z_STREAM_END if there 252 | was enough output space; if deflate returns with Z_OK, this function must be 253 | called again with Z_FINISH and more output space (updated avail_out) but no 254 | more input data, until it returns with Z_STREAM_END or an error. After 255 | deflate has returned Z_STREAM_END, the only possible operations on the 256 | stream are deflateReset or deflateEnd. 257 | 258 | Z_FINISH can be used immediately after deflateInit if all the compression 259 | is to be done in a single step.

If not all input can be processed (because there is not 327 | enough room in the output buffer), next_in is updated and processing 328 | will resume at this point for the next call of inflate(). 329 | 330 | - Provide more output starting at next_out and update next_out and avail_out 331 | accordingly. inflate() provides as much output as possible, until there 332 | is no more input data or no more space in the output buffer (see below 333 | about the flush parameter). 334 | 335 | Before the call of inflate(), the application should ensure that at least 336 | one of the actions is possible, by providing more input and/or consuming 337 | more output, and updating the next_* and avail_* values accordingly. 338 | The application can consume the uncompressed output when it wants, for 339 | example when the output buffer is full (avail_out == 0), or after each 340 | call of inflate().

The flushing behavior of inflate is 346 | not specified for values of the flush parameter other than Z_SYNC_FLUSH 347 | and Z_FINISH, but the current implementation actually flushes as much output 348 | as possible anyway. 349 | 350 | inflate() should normally be called until it returns Z_STREAM_END or an 351 | error.
