Furthermore, the list of transforms * + * to apply is broken, in that only half the required space * + * is allocated for the list. (It appears as though the * + * space is allocated for ASCII strings, but the strings are * + * written as unicode. As a result, only the first half of * + * the string appears.) So this is probably not too big of * + * a deal, at least until CHM v4 (MS .lit files), which also * + * incorporate encryption, of some description. * + ***************************************************************************/ + +/*************************************************************************** + * * + * This program is free software; you can redistribute it and/or modify * + * it under the terms of the GNU Lesser General Public License as * + * published by the Free Software Foundation; either version 2.1 of the * + * License, or (at your option) any later version. * + * * + ***************************************************************************/ + +#ifndef INCLUDED_CHMLIB_H +#define INCLUDED_CHMLIB_H + +#ifdef __cplusplus +extern "C" { +#endif + +/* RWE 6/12/1002 */ +#ifdef PPC_BSTR +#include +#endif + +#ifdef WIN32 +#ifdef __MINGW32__ +#define __int64 long long +#endif +typedef unsigned __int64 LONGUINT64; +typedef __int64 LONGINT64; +#else +typedef unsigned long long LONGUINT64; +typedef long long LONGINT64; +#endif + +/* the two available spaces in a CHM file */ +/* N.B.: The format supports arbitrarily many spaces, but only */ +/* two appear to be used at present. */ +#define CHM_UNCOMPRESSED (0) +#define CHM_COMPRESSED (1) + +/* structure representing an ITS (CHM) file stream */ +struct chmFile; + +/* structure representing an element from an ITS file stream */ +#define CHM_MAX_PATHLEN (512) +struct chmUnitInfo +{ + LONGUINT64 start; + LONGUINT64 length; + int space; + int flags; + char path[CHM_MAX_PATHLEN+1]; +}; + +/* open an ITS archive */ +#ifdef PPC_BSTR +/* RWE 6/12/2003 */ +struct chmFile* chm_open(BSTR filename); +#else +struct chmFile* chm_open(const char *filename); +#endif + +/* close an ITS archive */ +void chm_close(struct chmFile *h); + +/* methods for ssetting tuning parameters for particular file */ +#define CHM_PARAM_MAX_BLOCKS_CACHED 0 +void chm_set_param(struct chmFile *h, + int paramType, + int paramVal); + +/* resolve a particular object from the archive */ +#define CHM_RESOLVE_SUCCESS (0) +#define CHM_RESOLVE_FAILURE (1) +int chm_resolve_object(struct chmFile *h, + const char *objPath, + struct chmUnitInfo *ui); + +/* retrieve part of an object from the archive */ +LONGINT64 chm_retrieve_object(struct chmFile *h, + const struct chmUnitInfo *ui, + unsigned char *buf, + LONGUINT64 addr, + LONGINT64 len); + +/* enumerate the objects in the .chm archive */ +typedef int (*CHM_ENUMERATOR)(struct chmFile *h, + struct chmUnitInfo *ui, + void *context); +#define CHM_ENUMERATE_NORMAL (1) +#define CHM_ENUMERATE_META (2) +#define CHM_ENUMERATE_SPECIAL (4) +#define CHM_ENUMERATE_FILES (8) +#define CHM_ENUMERATE_DIRS (16) +#define CHM_ENUMERATE_ALL (31) +#define CHM_ENUMERATOR_FAILURE (0) +#define CHM_ENUMERATOR_CONTINUE (1) +#define CHM_ENUMERATOR_SUCCESS (2) +int chm_enumerate(struct chmFile *h, + int what, + CHM_ENUMERATOR e, + void *context); + +int chm_enumerate_dir(struct chmFile *h, + const char *prefix, + int what, + CHM_ENUMERATOR e, + void *context); + +#ifdef __cplusplus +} +#endif + +#endif /* INCLUDED_CHMLIB_H */ -- cgit v1.2.3
