Actually they are symbols in the kernel which is different than system
calls.
They can only be called from KEXT/KNE's (drivers).
System calls are calls which cross between userland and kernel.

Hi,
I am trying to use the blowfish encryption/decryption functions with
project
builder in an Cocoa Mac OS X application.
There is a header file <crypto/blowfish.h> in Kernel.framework and I can
compile with it. But when I link, I got the error "Undefined symbols:
_BF_set_key". So the blowfish functions cannot be found by the linker.
But I
cannot link against Kernel.framework because it has no libraries in it.
It
has only headers. I think that is because the "libraries" are system
calls
in this case. But how can I use blowfish? Where is the library with the
system call "stubs" to link against?
Regards,
Mani
