static int32 CompressMemoryBound

FName FormatName,
int32 UncompressedSize,

int32 CompressionData
&41;
Remarks
Thread-safe abstract compression routine to query memory requirements for a compression operation. This is the minimize size to allocate the buffer for CompressMemory (encoding). Use GetMaximumCompressedSize at decode to know how large a compressed buffer may be. The maximum possible bytes needed for compression of data buffer of size UncompressedSize
Parameters
| Name | Description |
|---|---|
| FormatName | Name of the compression format |
| UncompressedSize | Size of uncompressed data in bytes |
| Flags | Flags to control what method to use and optionally control memory vs speed |
| CompressionData | Additional compression parameter (specifies BitWindow value for ZLIB compression format) |
