int uid_close_queue | ( | void | ) |
This method closes the message queue and deletes it.
This | method returns 0 on success and -1 on error. |
int uid_open_queue | ( | const char * | q_name, |
int | flags, | ||
size_t | max_msgs | ||
) |
This method creates the message queue that holds events from the input devices.
[in] | q_name | is the name of the message queue |
[in] | flags | controls the behaviour of the queue |
[in] | max_msgs | specifies the maximum number of pending messages |
This | method returns 0 on success and -1 on error. |
void uid_print_message | ( | struct MW_UID_MESSAGE * | uid | ) |
This methods prints the specified UID message using printk
[in] | uid | points to the message to print |
void uid_print_message_with_plugin | ( | const rtems_printer * | printer, |
struct MW_UID_MESSAGE * | uid | ||
) |
This methods prints the specified UID message using your fprintf style method of choice.
[in] | RTEMS | printer |
[in] | uid | points to the message to print |
int uid_read_message | ( | struct MW_UID_MESSAGE * | m, |
unsigned long | timeout | ||
) |
This method reads a message from the queue. It waits up to the specified timeout in miliseconds. A timeout of 0 is a poll.
[in] | m | will be filled in with the received message |
[in] | timeout | is the maximum number of mulliseconds to wait |
This | method returns 0 on success and -1 on error. |
int uid_register_device | ( | int | fd, |
const char * | q_name | ||
) |
This method registers the device associated with fd to to insert data to the queue
int uid_send_message | ( | struct MW_UID_MESSAGE * | m | ) |
This methods writes a message to the queue.
[in] | m | is the message to send |
This | method returns 0 on success and -1 on error. |
