About LPSTR

[jack1234]

I have seen a lot of type LPSTR(and other like LPCSTR, etc) when coding using MFC.

I just know it is equivalent to char*, but what LPSTR exactly is?
(ie, is it a native type in C++, or a macro in C++, or a typedef in C++, or...)

It's a typedef.

Yes, windows tend to do that for alot of types, and sometimes theres no need for them, for example in one of the header files I found these:

#define CONST               const
typedef int                 INT;
typedef float               FLOAT;

and hunderds more.. ;)

Hmm I wonder...

typedef void VOID

I'm pretty sure that exists too.

I also love this one (not sure if its in Windows API or DirectX):

#define 1 TRUE
#define 0 FALSE
typedef int BOOL;

It's just a way to make types sort of case-insensitive. It may be a bit superfluous at times, but it's a neat thing to have.

#define 0 FALSE

Actually it would be

#define TRUE 1 
#define FALSE 0

the BOOL typedef'd as an int isn't actually so bad, it allows you to set your own returns values like:

#define FALSE		0
#define TRUE		1
#define OVERFLOW	2
#define FAIL		3
#define SUCCESS		4

any many more... :P

and can be more understood when returned as BOOL instead of int.

These typedefs and macros were created by MS team in early Windows era in the interests of portability.

Actually it would be

#define TRUE 1 
#define FALSE 0

Oh ya. Got confused with the typedefs.
