Hello,

As subject, as we know we can check the kernel config file through reading '/usr/src/kernels/`uname -r`/.config' (fedora distro), it's apparently to find out which config is open/close. but if I'd like do this in C program, how to do that, is there interface/func in some header file?

execve "zcat /proc/config.gz | grep CONFIG_XXX"

/proc/config.gz has been removed (not sure since which kernel version), also it's similar with checking '/usr/src/kernels/`uname -r`/.config'.

I'm not sure whether there is a C function in system headers file, that can recognize the special config option is open/close.

Thanks,
