Error Codes Symbian
specified object KErrGeneral -2 General (unspecified) error KErrCancel -3 The operation was cancelled KErrNoMemory -4 Not enough memory KErrNotSupported -5 The operation requested is not supported KErrArgument -6 An argument is out of range KErrTotalLossOfPrecision -7 This error arises when converting from an internal 96-bit real representation to a TReal32; the exponent of the internal representation is so small that the 32-bit real cannot contain it. KErrBadHandle -8 An invalid handle has been passed. A function involving a resource owned by a server or the kernel has specified an invalid handle. KErrOverflow -9 In the context of mathematical or time/date functions, indicates a calculation that has produced arithmetic overflow exceeding the bounds allowed by the representation. In the context of data transfer, indicates that a buffer has over-filled without being emptied soon enough. KErrUnderflow -10 In the context of mathematical or time/date functions, indicates a calculation that has produced a result smaller than the smallest magnitude of a finite number allowed by the representation. In the context of data transfer, indicates that a buffer was under-filled when data was required. KErrAlreadyExists -11 Already exists KErrPathNotFound -12 Unable to find the specified folder KErrDied -13 A handle refers to a thread that has died. KErrInUse -14 A requested resource is already in exclusive use. KErrServerTerminated -15 Client/server send/receive operation cannot run, because the server has terminated. KErrServerBusy -16 A client/server send/receive operation cannot run, because the server is busy handling another request. KErrCompletion -17 An operation is complete, successfully or otherwise. This code may be used to indicate that some follow on operation can take place. It does not necessarily indicate an error condition. KErrNotReady -18 A device required by an i/o operation is not ready to start operations. A common reason for returning this code is because a device has not been initialised, or has no power. KErrUnknown -19 Unknown error KErrCorrupt -20 Some media is not formatted properl

Code Review Qt Documentation Qt 4.8 Exception Safety with Symbian Contents What the problem is Qt calls to Symbian http://doc.qt.io/qt-4.8/symbianexceptionsafety.html Be careful with new and CBase Qt called from Symbian Common sense things Advanced technique Exception Safety with Symbian The following sections describe how Qt code can interoperate with Symbian's exception safety system. What the problem is Qt and Symbian have different exception systems. Qt works with standard C++ exceptions, whereas Symbian has error codes its TRAP/Leave/CleanupStack system. So, what would happen if you mix the two systems? It could go wrong in a number of ways. Clean-up ordering would be different between the two. When Symbian code leaves, the clean-up stack is cleaned up before anything else happens. After that, the objects on the call stack would error codes symbian be cleaned up as with a normal exception. So if there are any dependencies between stack-based and objects owned by the clean-up stack, there could be problems due to this ordering. Symbian's XLeaveException, which is used when Symbian implements leaves as exceptions, is not derived from std::exception, so would not be caught in Qt catch statements designed to catch std::exception. Qt's and standard C++'s std::exception derived exceptions result in program termination if they fall back to a Symbian TRAP. These problems can be solved with barrier macros and helper functions that will translate between the two exception systems. Use them, in Qt code, whenever calling into or being called from Symbian code. Qt calls to Symbian When calling Symbian leaving functions from Qt code, we want to translate Symbian leaves to standard C++ exceptions. The following help is provided: qt_symbian_throwIfError() takes a Symbian error code and throws an appropriate exception to represent it. This will do noth
