(SST) ShlWAPIFunctionInfo Version 1.0 |
|---|---|
| Developer Reference |
| Allocates the memory into which the version information should be copied. |
| Scope |
|---|
| Protected (i.e. the method can only be accessed from code in a descendant class or the unit it which it is implemented). |
| Syntax | |
|---|---|
| Function RetResourceVersionInfoBuf() : POINTER; VIRTUAL; | |
| Parameters | |
|---|---|
| None | |
| Return Values |
|---|
| Returns a pointer to the allocated buffer. |
| Remarks |
|---|
| The returned pointer and data are also available in the form of property ResourceVersionInfoBuf, and reading the property should be preferred to calling the RetResourceVersionInfoBuf function directly. |
| The function checks if a buffer has already been allocated, by comparing member variable fresourceinfobuffer to nil. If fresourceinfobuffer is still nil, the function reads property ResourceVersionInfoSize to determine the required buffer size. Provided the returned value is larger than zero (0), it calls the Delphi SDK procedure GetMem to allocate the memory and assign the returned pointer to member variable fresourceinfobuffer. |
| If a buffer already exists the function returns a pointer to the exisiting buffer. This also means that no size adjustments are made to the previously allocated memory. |
| The function handles all runtime library (RTL) exceptions raised during the allocation of the required memory. Should an exception be raised and handled/caught as a result of calling the Delphi SDK procedure GetMem, the function calls procdure SetLastErrorCode with a default error code of ERROR_OUTOFMEMORY (= 14). |
| The allocated buffer is freed in the destructor. |
| Requirements | |
|---|---|
| Unit | (Declared and implemented in) SSTNewUnit.pas |
| Library | SSTNewUnit.dcu/SSTNewUnit.obj |
| Unicode | Implemented as ANSI version only. |
