INFO: SizeofResource() Rounds to Alignment Size

ID: Q57808

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK)
Microsoft Win32 Software Development Kit (SDK)
Microsoft Windows 2000

SUMMARY

SizeofResource() returns the resource size rounded up to the alignment size. Therefore, if you have your own resource types, you cannot use SizeofResource() to get the actual resource byte count.

It has been suggested that this be changed to reflect the actual number of bytes in the resource so that applications can use SizeofResource() to determine the size of each resource. This suggestion is under review and will be considered for inclusion in a future release of the Windows Software Development Kit (SDK).
