[Dev-C++] Return values from static LPVOID functions

[Daniel G. <sp...@ho...>]

I'm looking through some code and I've found a function with the return type 
static LPVOID

static LPVOID SomeFunction()


and it has a return value that is an unsigned char*

return MyVal;  // An unsigned char*

How does this tally with LPVOID ? Can the return value by a pointer to 
anything if the return type is specified as LPVOID ?

[Per W. <pw...@ia...>]

LPVOID will normally just expand to void*, and any other pointer type will
be assignable to a void* pointer.

The LP is originally an inherritance from the 16-bit API of Windows 3.11
and below, where you had to differentiate between 16-bit and 32-bit
pointers. We MIGHT see that again in application programs, if someone
takes up the 48-bit far pointers supported by the 386 and higher
processors, but most probably the decision will be to only support > 4GB
for a single process on 64-bit processors. Most existing 32-bit solutions
for more than 4GB memory only lets the OS see all the memory, and limits
each process to less than 4GB.
