detecting kernel version via API or system call

[Michelangelo Calatino]

Hi folks, 
 
 I would like to check the kernel version, getting 
the same result as :

uname -r

but inside a C program.
Is there an API function or system call I can use ?
Otherwise I could always look into :

/usr/include/linux/version.h

but, perhaps there is shorter way ?
Thank you,

Michelangelo
