GetProcessHeaps
The GetProcessHeaps function obtains handles to all of the heaps that are valid for the calling
process.
DWORD GetProcessHeaps(
DWORD NumberOfHeaps,
| // maximum number of heap handles buffer can receive
| PHANDLE ProcessHeaps
| // points to buffer to receive array of heap handles
| );
|
|
Parameters
NumberOfHeaps
Specifies the maximum number of heap handles that can be stored into the
buffer pointed to by ProcessHeaps.
ProcessHeaps
Points to a buffer to receive an array of heap handles.
Return Values
The return value is the number of heap handles that are valid for the calling
process.
If the return value is less than or equal to NumberOfHeaps, it is also the number of heap handles stored into the buffer pointed to by ProcessHeaps.
If the return value is greater than NumberOfHeaps, the buffer pointed to by ProcessHeaps is too small to hold all the valid heap handles of the calling process.The
function will have stored no handles into that buffer. In this situation, use the
return value to allocate a buffer that is large enough to receive the handles,
and call the function again.
If the return value is zero, the function has failed, because every Win32
process has at least one valid heap, the process heap. To get extended error
information, call GetLastError.
Remarks
Use the GetProcessHeap function to obtain a handle to the process heap of the calling process. The GetProcessHeaps function obtains a handle to that heap, plus handles to any additional private
heaps created by calling the HeapCreate function.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
