77 * This is the actual code for the system call... it can't be static because
78 * it is exported to another part of the module... the only place it needs
79 * to be referenced is the sysent we are interested in.
81 * To write your own system call using this as a template, you could strip
82 * out this code and use the rest as a prototype module, changing only the
83 * function names and the number of arguments to the call in the module
86 * You would have to use the "-R" option of "ld" to ensure a linkable file
87 * if you were to do this, since you would need to combine multiple ".o"
88 * files into a single ".o" file for use by "modload".
