Hello, I'm currently using an IDE which builds c++ projects for several platforms (win32, windows mobile, symbian etc). This IDE doesn't keep a build dependency list and simply rebuilds the entire project every time. This wastes a lot of our time, which made us consider implementing a smarter build process: cpp files will be recompiled o...
WARNNING: Total certificate newbie I have a certificate that is used for server authentication and I want to check if that certificate is validate for the url that the server is publish on. for example: if the certificate is for *.myserver.com then any url that its host part ends with myserver.com is valid. What I would like is some...
I am looking to compare two arrays in google test. In UnitTest++ this is done through CHECK_ARRAY_EQUAL. How do you do it in google test? ...
Hi, In a template function, I like to determine the range for the value of its template type. For specific type, like int, INT_MAX and INT_MIN are what I want. But how to do the same for a template type? Thanks and regards! ...
I have a Win32 application that uses boost::asio and openssl library but it seems that they are not supported under WM, am I correct? Can anyone suggest WM API/library for WM Sockets, I need to connect to a server through SSL connection. Is the only option for me WinSocks + OpenSSL? ...
For instance why does most members in STL implementation have M or _ or __ prefix? Why there is so much boilerplate code ? What features C++ is lacking that would allow make vector (for instance) implementation clear and more concise? ...
Hi, Here is some code I'm writing in C++. There's a call to an addAVP() function dMessage.addAVP(AVP_DESTINATION_HOST, peer->getDestinationHost() || peer->getHost()); which has two versions: one overloaded in the second parameter to addAVP(int, char*) and another to addAVP(int, int). I find the C++ compiler I use calls the addAVP(int...
Hi, I have to come back once again to sockets in Symbian. Code to set up a connection to a remote server looks as follows: TInetAddr serverAddr; TUint iPort=111; TRequestStatus iStatus; TSockXfrLength len; TInt res = iSocketSrv.Connect(); res = iSocket.Open(iSocketSrv,KAfInet,KSockStream, KProtocolInetTcp); res = iSocket.SetOpt(...
class A { public: A(); ~A(); int X; }; A::A() { X = 5; int Y = 4; } //..... in another file A * objectOnHeap = new A(); In this case, since "objectOnHeap" is on the heap, is X also on the heap even though it wasn't specifically new'd up? And in this case Y is allocated on the stack (and of course goes out of scope), correc...
Hello, I need to implement the unary minus for a class. As the class is quite complicated, I must call the constructor in some way. If I try - ClassName ClassName::forUnaryMinus(){ ClassName retval(_parameters); //do stuff return retval; } The compiler complains - warning C4172: returning address of local variable or temp...
It is used in /usr/include/c++/4.3/stl_list.h on my system (current Ubuntu). ...
I was doing a quick performance test on a block of code void ConvertToFloat( const std::vector< short >& audioBlock, std::vector< float >& out ) { const float rcpShortMax = 1.0f / (float)SHRT_MAX; out.resize( audioBlock.size() ); for( size_t i = 0; i < audioBlock.size(); i++ ) { out[i] = (float...
Hi guys, For the past few days I have been attempting to write my own shell implementation but I seem to have gotten stuck on getting pipes to work properly. I am able to parse a line and fork off the commands between the pipes (ex: ls | sort) individually but can't seem to get them to pipe input from one into the other. I think I jus...
im required to write a function to overload the ==operator to compare width, height and colour. i need to return 'Y' if its equal and 'N' if its not. this is my code which i think its correct but keeps getting the error in the title. i've done searches and nothing came close to comparing 3 data as most examples are for comparing 2 da...
I found this piece of code on the site, it seems the author is long gone, anyway, I'm having hard time understanding the actual swap and how the reverse occurs: void strrev2(char *str) { if( str == NULL ) return; char *end_ptr = &str[strlen(str) - 1]; char temp; while( end_ptr > str ) ...
I was wondering why the following code doesn't compile: void foo_int(int *a) { } void foo_long(long *a) { } int main() { int i; long l; foo_long(&i); foo_int(&l); } I am using GCC, and neither calls work either in C or C++. Since it is a 32-bit system, both int and long are signed 32-bit integers (which can be verifi...
what is decaying of array? is there any relation to the array pointers? ...
We have several C++ projects that were built from the same codebase. There's a lot of similarities and common code between them but they were developed independently; source was not shared in any way. Classes and files will have been renamed even if the underlying code hasn't changed and individual lines will have been tweaked, changed a...
I am using CPPUnit to test a class in my program. This class (SCriterionVal) is somewhat unique because it has conversion operators for a lot of types (it's essentially a dynamic type value class). When I compile test cases that test it using CPPUNIT_ASSERT_EQUAL(), I get compilation errors about "operator<< is ambiguous" from one of t...
for (unsigned int i = 1; i <= 100; i++) { if (i & 0x00000001) { std::cout << i<<","; } } why does (and how): if( i & 0x00000001 ) figure out the odd number? ...
