13 | This module supplies an UnZip engine for use directly from C/C++ |

14 | programs. The functions are: |

18 | int UzpMain(int argc, char *argv[]); |

||
22 | int UzpUnzipToMemory(char *zip, char *file, UzpOpts *optflgs, |
||
23 | UzpCB *UsrFuncts, UzpBuffer *retstr); |
||
24 | |||
25 | non-WINDLL only (a special WINDLL variant is defined in windll/windll.c): |
||
26 | int UzpGrep(char *archive, char *file, char *pattern, int cmd, int SkipBin, |

27 | UzpCB *UsrFuncts); |

29 | OS/2 only (for now): |
||
30 | int UzpFileTree(char *name, cbList(callBack), char *cpInclude[], |
||
31 | char *cpExclude[]); |
||
32 | |||
33 | You must define `DLL' in order to include the API extensions. |
