17.2 Modified Functions

These functions are not fully implemented, and return an error condition if called: adjtime, getdirentries, sbrk, and flock.

These functions are trivially implemented, and are primarily intended to satisfy linktime dependencies (for example, getuid always returns zero): geteuid, getuid, seteuid, setuid, getgid, and setgid.

A small number of functions have default implementations that call panic if they are executed. They are provided in order to saitisfy linktime dependencies, but should not actually be called. This is sometimes useful when converting Unix applications into OSKit kernels. They are execve, fork, vfork, wait4, and waitpid.
