qFromBigEndian(...) not found??

[maverick_pol]

Hi,

I have trivial question:
I can use all the functions from the QtGlobal, but when I try to use one of these

T qFromBigEndian ( const uchar * src )
T qFromBigEndian ( T src )
T qFromLittleEndian ( const uchar * src )
T qFromLittleEndian ( T src )

T qFromBigEndian ( const uchar * src )
T qFromBigEndian ( T src )
T qFromLittleEndian ( const uchar * src )
T qFromLittleEndian ( T src )

To copy to clipboard, switch view to plain text mode 

I get an error pointing that the functions' declarations cannot be found( as I haven't included the header).

I have checked it many times I can use other functions and features from this QtGlobal, but not the mentioned functions.

{ADDED}
I have checked the global.h and I have no declaration of the qFromBigEndian(...) etc.
Where are these functions declared then?

Thanks
