new/delete is perfectly cross-platform. All platforms (that the C api supports anyway) these days have C++ compilers with standard STL implementations. gcc is one of them, and works with RTL as well. As for structure member byte alignment, that depends entirely on your compiler. 8 bytes is necessary for MS compilers (and I think it's the default), because that's what the C API uses. I don't know if it's the same on Linux, but I do know the default gcc byte alignment is not the right one, at least on Linux! For gcc, you have to set -malign-xxx (I don't remember exactly...try -malign-double). Even if you get the alignment right, you still have to deal with C runtime version, static/dynamic linkage, and debug/release matching. If you don't have the exact same major version of the compiler that BMC used to build the API client libraries, and really understand what options to use, don't trust it to free memory you allocate!

I have compiled 'driver' with MSVS.NET2005 and memory allocation problem has occurred. But It take place in debug mode (when I press 'F5'). If I compile program and execute it by running .exe file or pressing 'CTRL+F5', 'driver' and my own program execute without errors. In 'driver' project properties C/C++ -> Code Generation -> Basic Runtime Checks has been set to 'default', in my project to 'Both (/RTC1, equiv. to /RTCsu)'. My program run without errors (in non-debug mode, of cause) when I changed my properties like 'driver'. If I comment all except the QualifierStruct's initialization and ARFree, I get the same error. It's all the same. I will use my own free function or use both functions in the following way for example: #ifndef FREE_AR free(qualifier.u.andor.operandLeft->u.relOp); free(qualifier.u.andor.operandRight->u.relOp); free(qualifier.u.andor.operandLeft); free(qualifier.u.andor.operandRight); #else FreeARQualifierStruct(&qualifier, FALSE); #endif Answer to Dan. I don't want to use new/delete because program will be less cross-platform. And I don't know where I can know how to define 'structure byte alignment' from? __20060125_______________________This posting was submitted with HTML in it___ _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org ARSlist:"Where the Answers Are"
