[Confuse-devel] Problem with libConfuse in Visual Studio 2008

[Honza Bajer]

 Hi,

Im trying to port my Linux application to Windows and I have a problem with calling cfg_init() from libconfuse.dll. Loading of this dll with LoadLibraryA() and getting methods from dll with GetProcAddress() is without any problem or error.

typedef cfg_t *(*CFG_INIT_FPTR)(cfg_opt_t *opts, cfg_flag_t flags);

CFG_INIT_FPTR cfg_init;

cfg_init = (CFG_INIT_FPTR)GetProcAddress(hinstLib, DLLSYM("cfg_init"));

if(cfg_init)
 {
        cfg = cfg_init(opts, 0);
}


I figured out, that problem is probably in the structures for this method (In Ubuntu it works without any problem) because with expamle structure from wincfgtest.c everything works fine:


cfg_opt_t opts[] = {
        CFG_BOOL("bool", cfg_false, 0),
        CFG_STR("string", "default test string", 0),
        CFG_INT("number", 17, 0),
        CFG_FLOAT("float", 6.789, 0),
        CFG_FUNC("message", &cb_message),
        CFG_END()
    };


but with my structures for cfg_init() a get an error when I try to call this method:

"Access Violation Exception" and something about memory corruption

My structures are these:

cfg_opt_t bookmark_us[] = {
        CFG_INT("port", /*PORT_UZIVATEL*/  8900, 0),
        CFG_BOOL("standard_connection", cfg_true, 0),
        CFG_INT("ssl_port", /*PORT_UZIVATEL_SSL*/  5, 0),
        CFG_INT("max_users", /*MAX_USERS*/  10, 0),
        CFG_INT("max_ssl_users", /*MAX_SSL_USERS*/  10, 0),
        CFG_BOOL("ssl", cfg_true, 0),
        CFG_INT("sec_level", /*SECURITY_LEVEL*/  1, 0),
        CFG_INT("sec_depth", /*SECURITY_DEPTH*/  1, 0),
        CFG_STR("authority", "nic", 0),
        CFG_STR("certificate", /*CERTT*/  "certifikat", 0),
        CFG_STR("key", /*KLIC*/  "klic", 0),
        CFG_STR("hosts", "hosts", 0),

        CFG_END()
       };


    cfg_opt_t bookmark_cl[] = {
        CFG_INT("port", /*PORT_KLIENT*/  8888, 0),
        CFG_INT("max_clients", /*MAX_CLIENTS*/  100, 0),
        CFG_INT("wake_port", /*WAKE_PORT*/  9, 0),
        CFG_INT("wake_timeout", /*WAKE_TIM*/  5, 0),
        CFG_INT("wake_repeat", /*WAKE_REPEAT*/  2, 0),
        CFG_INT("timeout", /*TIMEOUT* /  5, 0),
        CFG_BOOL("ssl", cfg_true, 0),
        CFG_INT("sec_level", /*SECURITY_LEVEL*/  1, 0),
        CFG_INT("sec_depth", /*SECURITY_DEPTH*/  1, 0),
        CFG_STR("authority", "nic", 0),
        CFG_STR("certificate", "ccc"  /*CERTT*/, 0),
        CFG_STR("key", /*KLIC*/  "kkk", 0),
        CFG_INT("ping_timeout", /*PING_TIMEOUT*/  2, 0),
        CFG_INT("ping_repeat", /*PING_REPEAT*/  5, 0),

        CFG_END()
        };


    cfg_opt_t opts[] = {

    CFG_INT("logging", /*DEPTH_OF_LOGGING*/  1, /*CFGF_NONE*/  0),
    CFG_STR("user_name", "primary_user", /*CFGF_NONE*/  0),
    CFG_STR("client_name", "primary_client", /*CFGF_NONE*/  0),
    CFG_BOOL("file_log", cfg_false, /*CFGF_NONE*/  0),
    CFG_BOOL("system_log", cfg_true, /*CFGF_NONE*/  0),
    CFG_STR("log_file_name", /*LOGFILE*/  "string", 0),
    CFG_SEC("section_user", bookmark_us,  CFGF_MULTI | CFGF_TITLE),
    CFG_SEC("section_client", bookmark_cl,  CFGF_MULTI | CFGF_TITLE),

       CFG_END()
    };


Commented parts are my default defined values. Im using Visual Studio 2008 (Visual C++) with libConfuse 2.7. I really dont know, where is the problem.

Thans for any advice.
