C library? Where do I find its > definition (not declaration)? libc provides syscall(). Definition can be found in syscall(2). Use is like this (implementing inotify_add_watch()): #include <sys/syscall.h> #include <unistd.h> #include <linux/inotify.h> static int inotify_add_watch(int fd, const char *path, unsigned int mask) { return syscall(__NR_inotify_add_watch, fd, path, mask); } > What is an application supposed to do if it does not want to use the > library? The same as an application should do if it wants to use printf() but not libc: implement it yourself. Erik -- They're all fools. Don't worry.
