Expand description
ZSTD_DCtx_setMaxWindowSize() : Refuses allocating internal buffers for frames requiring a window size larger than provided limit. This protects a decoder context from reserving too much memory for itself (potential attack scenario). This parameter is only useful in streaming mode, since no internal buffer is allocated in single-pass mode. By default, a decompression context accepts all window sizes <= (1 << ZSTD_WINDOWLOG_LIMIT_DEFAULT) @return : 0, or an error code (which can be tested using ZSTD_isError()).
