Class TVendorId

class TVendorId;

Description

A class used to represent the Vendor ID of a process or executable image

Constructors and conversion operators are provided to enable conversion of this class to and from both TUint32 and TUid objects.

Because this class has non-default constructors, compilers will not initialise this objects at compile time, instead code will be generated to construct the object at run-time. This is wastefull, and Symbian OS DLLs are not permitted to have such uninitialised data. To overcome these problems a macro is provided to construct a const object which behaves like a TSecureId. This is _LIT_VENDOR_ID. This macro should be used where it is desirable to define const TSecureId objects, like in header files. E.g. Instead of writing:

    const TVendorId MyId=0x1234567

use

    _LIT_VENDOR_ID(MyId,0x1234567)
