Hi, I've seen void (*sv_prepsyscall)(struct trapframe *, int *, u_int *, cad= dr_t *); field in struct sysentvec defined in sys/sysent.h; I've seen it's ca= ll be the current process in syscall interrupt 0x80 handling and it seems to= set number of arguments and base pointer for syscall arguments. It's not a comment in the code, somebody could tell me what is the task of this fi= eld? thanks rookie
