| [9] | 1 | /* Function prototypes for the system library. The prototypes in this file
|
|---|
| 2 | * are undefined to do_unused if the kernel call is not enabled in config.h.
|
|---|
| 3 | * The implementation is contained in src/kernel/system/.
|
|---|
| 4 | *
|
|---|
| 5 | * The system library allows to access system services by doing a kernel call.
|
|---|
| 6 | * System calls are transformed into request messages to the SYS task that is
|
|---|
| 7 | * responsible for handling the call. By convention, sys_call() is transformed
|
|---|
| 8 | * into a message with type SYS_CALL that is handled in a function do_call().
