F* Function: int do_kbd (cmd_tbl_t *cmdtp, int flag,
|
||||||
|
F* int argc, char *argv[]) P*A*Z*
|
||||||
|
*
|
||||||
|
P* Parameters: cmd_tbl_t *cmdtp
|
||||||
|
P* - Pointer to our command table entry
|
||||||
|
P* int flag
|
||||||
|
P* - If the CMD_FLAG_REPEAT bit is set, then this call is
|
||||||
|
P* a repetition
|
||||||
|
P* int argc
|
||||||
|
P* - Argument count
|
||||||
|
P* char *argv[]
|
||||||
|
P* - Array of the actual arguments
|
||||||
|
P*
|
||||||
|
P* Returnvalue: int
|
||||||
|
P* - 0 is always returned.
|
||||||
|
*
|
||||||
|
Z* Intention: Implement the "kbd" command.
|
||||||
|
Z* The keyboard status is read. The result is printed on
|
||||||
|
Z* the console and written into the "keybd" environment
|
||||||
|
Z* variable.
