Function Documentation

native_async_read_add_handler()

void native_async_read_add_handler	(	int	fd,
		void *	arg,
		native_async_read_callback_t	handler
	)

start monitoring of file descriptor

Parameters

[in]	fd	The file descriptor to monitor
[in]	arg	Pointer to be passed as arguments to the callback
[in]	handler	The callback function to be called when the file descriptor is ready to read.

native_async_read_add_int_handler()

void native_async_read_add_int_handler	(	int	fd,
		void *	arg,
		native_async_read_callback_t	handler
	)

start monitoring of file descriptor as interrupt

Parameters

[in]	fd	The file descriptor to monitor
[in]	arg	Pointer to be passed as arguments to the callback
[in]	handler	The callback function to be called when the file descriptor is ready to read.

native_async_read_cleanup()

void native_async_read_cleanup

(

void

)

shutdown asynchronous read system

This deregisters SIGIO signal handler.

native_async_read_continue()

void native_async_read_continue

(

int

fd

)

resume monitoring of file descriptors

Call this function after reading file descriptors.

Parameters

[in]

fd

The file descriptor to monitor

native_async_read_remove_handler()

void native_async_read_remove_handler

(

int

fd

)

stop monitoring of file descriptor

Parameters

[in]

fd

The file descriptor to stop monitoring

native_async_read_setup()

void native_async_read_setup

(

void

)

initialize asynchronous read system

This registers SIGIO signal handler.
