这个错误通常发生在使用zlib库进行数据解压缩时。它是由于输出缓冲区(d_buf)的大小不足以保存所有的解压缩数据所导致的。解决方法是增加输出缓冲区的大小。示例代码如下：

z_stream strm; int ret; int CHUNK_SIZE = 1024; //每次解压的块大小 unsigned char in[CHUNK_SIZE]; unsigned char out[CHUNK_SIZE]; strm.zalloc = Z_NULL; strm.zfree = Z_NULL; strm.opaque = Z_NULL; strm.avail_in = 0; strm.next_in = Z_NULL; ret = inflateInit(&strm); if (ret != Z_OK) { printf("初始化inflate失败.\n"); exit(1); } /解压缩数据/ do { strm.avail_in = fread(in, 1, CHUNK_SIZE, source); //从文件中读取块 if (ferror(source)) { (void)inflateEnd(&strm); printf("读取文件失败.\n"); exit(1); } if (strm.avail_in == 0) break; strm.next_in = in; do { strm.avail_out = CHUNK_SIZE; strm.next_out = out; ret = inflate(&strm, Z_NO_FLUSH); assert(ret != Z_STREAM_ERROR);
switch (ret) { case Z_NEED_DICT: ret = Z_DATA_ERROR;
case Z_DATA_ERROR: case Z_MEM_ERROR: (void)inflateEnd(&strm); printf("内存错误.\n"); exit(1); } //写入数据到输出文件 unsigned have = CHUNK_SIZE - strm.avail_out; if (fwrite(out, 1, have, dest) != have || ferror(dest)) { (void)inflateEnd(&strm); printf("写入文件失败.\n"); exit(1); } } while (strm.avail_out == 0); } while (ret != Z_STREAM_END);
/释放内存/ (void)inflateEnd(&strm); fclose(source); fclose(dest);
