DosFreeResource (OS/2 1.x)

This call frees a resource loaded by DosGetResource2.

Syntax
DosFreeResource (ResAddr)

Parameters

 * ResAddr (PBYTE) - input : The address of the resource to free.

Return Code

 * rc (USHORT) - return:Return code descriptions are:
 * 0 NO_ERROR
 * 6 ERROR_ACCESS_DENIED

Remarks
DosFreeResource is used to free resources obtained with DosGetResource2.

After the last reference to a resource is freed, the memory becomes available for reuse by the system. However, the memory is not reused until the system determines it cannot satisfy a memory allocation request. This allows the resource to remain in memory in case the process issues another DosGetResource2 call. The system thus avoids having to reread the contents of the resource from disk.
