Hello For the access to IGT+ (Bankingsystem), I am writing a Module in Perl. What I have is: 1.) static library libhl_api.a 2.) a headerfile igt_hl_api.h
A part of the content is as below: <BEGIN CODE> /* Directions */ #define IGT_HL_DIR_INCOM 0 /* IGT --> Host */ #define IGT_HL_DIR_OUTGO 1 /* Host --> IGT */ #define IGT_HL_MIN_ERROR -3000 /* Error Codes returned from API functions */ #define IGT_HL_WRONG_DIR (IGT_MIN_ERROR+1) #define IGT_HL_WRONG_HOST (IGT_MIN_ERROR+2) #define IGT_HL_WRONG_IP (IGT_MIN_ERROR+3) #define IGT_HL_WRONG_PORT (IGT_MIN_ERROR+4) #define IGT_HL_WRONG_TIMEOUT (IGT_MIN_ERROR+5) #define IGT_HL_WRONG_WINDOW (IGT_MIN_ERROR+6) #define IGT_HL_OP_IN_PROGRESS (IGT_MIN_ERROR+7) #define IGT_HL_NO_INIT (IGT_MIN_ERROR+8) #define IGT_HL_NO_CONNECTION (IGT_MIN_ERROR+9) #define IGT_HL_LOGIN_TIMEOUT (IGT_MIN_ERROR+10) #define IGT_HL_ACK_TIMEOUT (IGT_MIN_ERROR+11) #define IGT_HL_MSG_TIMEOUT (IGT_MIN_ERROR+12) #define IGT_HL_SOCKET_ERROR (IGT_MIN_ERROR+13) #define IGT_HL_NAK_RECEIVED (IGT_MIN_ERROR+14) #define IGT_HL_WRONG_ACK (IGT_MIN_ERROR+15) #define IGT_HL_MESSAGE_ERROR (IGT_MIN_ERROR+16) #define IGT_HL_NO_MSG_OPEN (IGT_MIN_ERROR+17) #define IGT_HL_NO_MEMORY (IGT_MIN_ERROR+18) /* Insufficient memory or other resource */ #define IGT_HL_WRONG_DUPL (IGT_MIN_ERROR+19) #define IGT_HL_WRONG_ROUTE (IGT_MIN_ERROR+20) #define IGT_HL_DISCONNECTED (IGT_MIN_ERROR+50) #define IGT_HL_NOT_IMPLEMENTED (IGT_MIN_ERROR+100) #define IGT_HL_OK 1 #define IGT_HL_NOK -1 /* Trace Levels */ #define IGT_HL_NO_TRACE 0x00 #define IGT_HL_ERR_TRACE 0x01 #define IGT_HL_MIN_TRACE 0x02 #define IGT_HL_MSG_TRACE 0x04 #define IGT_HL_MAX_TRACE 0x08 #define IGT_HL_ALL_TRACE 0x0F #define IGT_HL_MAX_TIMEOUT 100000 #define IGT_HL_MAX_WINDOW 1 #define IGT_HL_MIN_WINDOW 1 #define IGT_HL_MIN_PORT 1024 #define IGT_HL_MAX_PORT 65535 <END CODE> These constants are needed in the module. I created the first prototype with h2xs an modified the Makefile.PL, so that the binding of the static library works. The methods of the new module banking::igtplus are working, only with the constants I get problems. For example the use of banking::igtplus::IGT_HL_MSG_TIMEOUT causes a segmentation fault. but not the use of banking::igtplus::IGT_HL_OK. From where this comes from? What can I do? Is it possible to define these constants in igtplus.pm, and how must I do that? Here some additional files: const-xs.inc: ------------- void constant(sv) PREINIT: #ifdef dXSTARG dXSTARG; /* Faster if we have it. */ #else dTARGET; #endif STRLEN len; int type; IV iv; /* NV nv; Uncomment this if you need to return NVs */ /* const char *pv; Uncomment this if you need to return PVs */ INPUT: SV * sv; const char * s = SvPV(sv, len); PPCODE: /* Change this to constant(aTHX_ s, len, &iv, &nv); if you need to return both NVs and IVs */ type = constant(aTHX_ s, len, &iv); /* Return 1 or 2 items.
