what does the WINAPI macro do?

21-Mar-06 23:43

looking at the MSDN[^], i think so
what you have to do for that is prepend the file name with \\<server>\...

int WINAPI function1(param);

int is the return value,function1 is teh function name,
then what does WINAPI do?

It's a calling convention for system functions. WINAPI expands to _stdcall.

It's a macro which expands to the appropriate calling convention. It's a macro so it can be defined differently on different platforms. On x86 based platforms it's __stdcall but on others it could be defined differently.

hi i'm working in vc++ from last one month.i'm working on a Project.
In which i have made a Web Browser.
My project need some more points.which i'm not getting these are:

1.Communication from the Browser to the web application is done by means of sending XML data using an HTTP POST request.
2.After the web application has received this request, it processes it and sends a redirect to the Browser.

Please help how can i implement these point.
Thanx in advance

convert 4 chars to __int32

big_denny_20021-Mar-06 21:44

21-Mar-06 21:44

hi all

I have for example 4 char variables

char c[4] = {'a','a','a','a'};

and one __int32 variable

__int32 x;

I want to write c[4] contents(binary) to x.

using shift left and & operations but I cant.

can someone help ?

toxcct21-Mar-06 21:59

2 ways :

__int32 i = c[0] +
            c[1] << 8 +
            c[2] << 16 +
            c[3] << 24;

the second one is more exotic :

union {
    char c[4];
    __int32 i;
} u;

hi thank you, but first is not working ?

__int32 x = 0;
char s[4] = {'a','a','a','a'};
x = s[0]+s[1]<<8+s[2]<<16+s[3]<<24; 
cout<<x;

when i run the proram i get such output x = 0

the second variant is not working correctly too, I get output : 1633771873 instead of 3267543746

thanks

i don't know why the 1st is not working... it should !!
however, be sure that that operator<<() is overloaded for __int32

for the union solution, it works because the memory blocks overlap, so your int is automatically filled with what you write in your char[4]...

I was wrong the result was correct.

As I said I had array of four chars

char s[4] = {'a','a','a','a'}

integer value of 'a' = 97 (1100001)

theretfore the result was correct

01100001 01100001 01100001 01100001 (1633771873)

thanks to everybody

toxcct21-Mar-06 22:58

21-Mar-06 22:58

as nibu said, how can you be sure it prints the incorrect value ?

if printf("%X", x) displays 0x61616161 (1633771873 in decimal), then everything is ok (according that 'a' is 0x61)

Fine on a little endian architecture but would fail on big endian.
