Detailed Description

Function Documentation

◆ uid_close_queue()

int uid_close_queue ( void  )

This method closes the message queue and deletes it.

Return values
Thismethod returns 0 on success and -1 on error.

◆ uid_open_queue()

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.

Parameters
[in]q_nameis the name of the message queue
[in]flagscontrols the behaviour of the queue
[in]max_msgsspecifies the maximum number of pending messages
Note
The message queue is from the Classic API.
Return values
Thismethod returns 0 on success and -1 on error.

◆ uid_print_message()

void uid_print_message ( struct MW_UID_MESSAGE uid)

This methods prints the specified UID message using printk

Parameters
[in]uidpoints to the message to print

◆ uid_print_message_with_plugin()

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.

◆ uid_read_message()

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.

Parameters
[in]mwill be filled in with the received message
[in]timeoutis the maximum number of mulliseconds to wait
Return values
Thismethod returns 0 on success and -1 on error.

◆ uid_register_device()

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

◆ uid_send_message()

int uid_send_message ( struct MW_UID_MESSAGE m)

This methods writes a message to the queue.

Parameters
[in]mis the message to send
Return values
Thismethod returns 0 on success and -1 on error.
