uint8,uint16,uint32???

[Yashas]

What are these?
Are those a C feature or should we define it, for example unsigned short int uint8.
i find those most of the code in osdev.

They're typedefs, often used for portability.

Code: Select all

typedef unsigned char uint8;
typedef unsigned short int uint16;
typedef unsigned int uint32;
typedef unsigned long int uint64;

EDIT: Added semicolons (Oops! I'm not much of a C guy, more into ASM)

[Yashas]

What are they usedfor and can we use unsigned int instead of unsigned short int?

[Unkn0wn1]

Depends. You in real mode?

EDIT: They are used so that you only really have to use a different compiler and ASM on different platforms. You can change those typedefs as needed in each arch

Mine is protected mode(32 bit) vey powerful with ATA,IDE,VGA.But i never used these so i wanted to know what are those.

[Unkn0wn1]

Then no. Long is twice CPU-bit, Short is half, char is 8 bits (Size of an ASCII character...)

I state it in this thread as well. I doubt you got all those features. A disk image would be good, or source, as proof

[Yashas]

Tell me which driver you want ATA,AHCI,IDE(Comes in AHCI),NTFS(Little Dumb can just read)

Even i kno long is twice.I was showing some i did not kno the number 8 in the uint8 was the niumber of bits.

To be honest id love to see some ntfs code I have some other stuff you don't that we could "trade"

[Yashas]

Just wait for a week I will post it here.Becaz i hav just started.
And also i ahv posted the base of the NTFS Code somewhere the forume today.

Mostly it the Keyboard Topic

Then no. Long is twice CPU-bit, Short is half, char is 8 bits (Size of an ASCII character...)

Wow, talk about the blind leading the blind.

Ooops... Well, I haven't really got into that stuff, and in this case, it is, so I kinda made stupid assumptions...
