| /* Function prototypes for the system library.  The prototypes in this file

|  * are undefined to do_unused if the kernel call is not enabled in config.h. 
 | |
|  * The implementation is contained in src/kernel/system/.  
 | |
|  *
 | |
|  * The system library allows to access system services by doing a system call.
 | |
|  * System calls are transformed into request messages to the SYS task that is 
 | |
|  * responsible for handling the call. By convention, sys_call() is transformed 
 | |
|  * into a message with type SYS_CALL that is handled in a function do_call().
