PULONG buffer Address of buffer for results. See DQPS.H
for the layout.
USHORT buffer_size Size of result buffer.
This function is a slightly altered version of the function of the same name that was present in OS/2 1.x, and which formed the basis of the PSTAT program. Though it remains a 16-bit function call, returning data formatted for a 16-bit application, it is nonetheless different from the original OS/2 1.x function in that the data structure returned is much more complete and is easier to use.
Note: Because this function remains a 16-bit version, the data buffer provided to it must be allocated with the OBJ_TILED attribute and cannot exceed 64K in size. There are times when 64K is not enough for the entire data structure, in which case the structure is truncated. This can lead to memory access violations upon trying to scan the structure. To avoid this problem you might want to use the DosQuerySysState function instead.
