Assertion`s<d_bufsize'failed（s小于d_bufsize的断言失败）
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);
