XbZ_DeRef(<nPointer>) --> cString
|
<nPointer>
|
<nPointer> is a pointer to a string, which is usually returned by a DLLCall() or DLLExecuteCall() function.
|
This function returns the String value to which <nPointer> is pointing.
|
This function returns a string from <nPointer>. DLLCall() and DLLExecuteCall() automatically de-reference pointers that are returned. However, if pointer-to-pointers are returned, only the first level of indirection is resolved, and you get left with a pointer (which is seen in Xbase++ as a number). This function is the XBPPGDEREF() function from the file "PSQLSupp.obj" file and is simply mapped to XbZ_DeRef() with a #pragma directive!
