But If you mean GNU libc aka. glibc then this is what you are looking for: https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/nptl/fork.c;h=1a68cbd6476b3268b5b7ac09ae60c35ce7069219;hb=HEAD#l47 __libc_fork() calls clone() syscall internally using a bit of assembler magic. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
