oslDebug both text and variable in one line of code?

[madman666]

I am wanting to print both text and a veriable in the same print out. How is this done using oslib?

I have tried using + and << and .. between the text and variable but I keep getting errors when I compile my code. these are the all different ways I have done this in other script language.

for example I would like it say in a Debug message "Active Location X=0 Y=0"

oslDebug("Active Location X=" + x + " Y=" + y);

and

oslDebug("Active Location X=" << x << " Y=" << y);

and

oslDebug("Active Location X=" .. x .. " Y=" .. y);

all do not work.

other then making a string and adding up all the parts, is there a easier way to do this?

I have searched and have not found anything

^works with a String class (with overloaded "+" operator) (which is not included in sdk)
you can use sceDebugScreenprintf("X=%i",x); .
or if the functions doesnt have char format use :

char *str;
int a=10,b=20;
sprintf(str,"%i x 2 = %i",a,b);
oslDebug(str);
//Result is : 10 x 2 = 20

<< only works with cout/cin (std::cout / std::cin in psp programming)
i dont know any other way to do it ...
EDIT: you can make your own function . to find out how to write it take a look at Stinkee2's EGPLib

or just ask me

Spoiler:

#include <stdarg.h>
char *ToString(const char *Text,...)
{
     va_list Args;
     va_start(Args,Text);
     char str[1001] = {'\0'};
     vsprintf(str,Text,Args);
     va_end(Args);
     return str;
}

thats just from memory though because Im not at my laptop right now.

shivers.. i feel a buffer over-run coming.

How would you have done it?

if that looks like im trying to be a dick thats not how I meant it,
I'm just curious so that I can fix any problems with my code.

lol i wouldn't have thought you were being a dick.

anyway, you just need to add some checks(at least) for your char array.
arrays + pointers = dangerous if not handle correctly.

your code for example. (with comments)

#include <stdarg.h>
char *ToString(const char *Text,...)
{
     va_list Args;
     va_start(Args,Text);
     char str[1001] = {'\0'}; //what if the Text pointer points to a longer string?
     vsprintf(str,Text,Args); //possible over-run?
     va_end(Args);
     return str;
}

was gonna say something here... don't remember what.

anyway i would do it like..

#include <stdarg.h>
#include <string.h>
char *ToString(const char *Text,...)
{
    va_list Args;
    va_start(Args,Text);
    char* str = new char[strlen(Text)];
    vsprintf(*str,Text,Args);
    va_end(Args);
    delete str;
    return str;
}

i think. anyway, that should grantee a no overflow situation.

were you going to say something about vsNprintf? I could have used that and set the size to 1000. I dont know why I didnt think to though.

Your a genious!
Why didnt I think of that?

[madman666]

Thanks guys you helped alot.

this will be my first attempt at a C++ program.

I have created stuff with Java and LUA(WOW Plug-ins). so overall the codding is going good as the basics are all the same its just the little things like the Strings and learning what I can do with the oslib that I have been hanging up on.

I should have a working Alpha sometime tonight. Then Ill start working on the features.

The result of the first example is undefined unless you make it static , but then if more than 1 ptrs point to it , they will contain the same data.

The second example will crash because you delete the string.

The most efficient approach is a buffered string class/library that will reallocate the buffer
only when needed.

Good luck programming .

@Brick:

Thanks, I will try that tomorrow.
