api.c
This module supplies a Zip dll engine for use directly from C/C++
programs.
The entry points are:
ZpVer *ZpVersion(void);
int EXPENTRY ZpInit(LPZIPUSERFUNCTIONS lpZipUserFunc);
BOOL EXPENTRY ZpSetOptions(LPZPOPT Opts);
ZPOPT EXPENTRY ZpGetOptions(void);
int EXPENTRY ZpArchive(ZCL C);
This module is currently only used by the Windows dll, and is not used at
all by any of the other platforms, although it should be easy enough to
implement this on most platforms.
