Overview
The CompressFile function uses the common zlib compression library to compress a file.
Syntax/Parameters
Syntax
int = CompressFile ( string source, string destination, [int level] );
Parameters
source
A string specifying a qualified source filename to compress. For maximum flexibility, this file is opened with read access and share write/read.
destination
A string specifying a qualified destination filename to compress. If a file of the same name already exists, it is overwritten.
level
An optional int specifying the type or level of compression. If omitted, the default compression is used.
Return Value
Returns an int as ERROR_NONE or a formatted error code on failure. The ERROR_DT_SOURCE (0x00100000) and ERROR_DT_DESTINATION (0x00200000) bits may be set to identify an error with a specific file operation.
Remarks
The level codes are as follows:
| Define | Bitwise Value | Description | ||||
| ZLIB_NO_COMPRESSION | 0 | No compression | ||||
| ZLIB_BEST_SPEED | 1 | Best speed | ||||
| ZLIB_BEST_COMPRESSION | 9 | Best compression | ||||
