3  * dvb_ringbuffer.h: ring buffer implementation for the dvb driver
30  * struct dvb_ringbuffer - Describes a ring buffer used at DVB framework
37  * @queue: Wait queue used by ringbuffer clients to indicate when buffer
55  * dvb_ringbuffer_init - initialize ring buffer, lock and queue
58  * @data: pointer to the buffer where the data will be stored
59  * @len: bytes from ring buffer into @buf
65  * dvb_ringbuffer_empty - test whether buffer is empty
72  * dvb_ringbuffer_free - returns the number of free bytes in the buffer
76  * Return: number of free bytes in the buffer
81  * dvb_ringbuffer_avail - returns the number of bytes waiting in the buffer
85  * Return: number of bytes waiting in the buffer
94  * Resets the read and write pointers to zero and flush the buffer.
105  * dvb_ringbuffer_flush - flush buffer
112  * dvb_ringbuffer_flush_spinlock_wakeup- flush buffer protected by spinlock
120  * DVB_RINGBUFFER_PEEK - peek at byte @offs in the buffer
139  * dvb_ringbuffer_read_user - Reads a buffer into a user pointer
142  * @buf: pointer to the buffer where the data will be stored
143  * @len: bytes from ring buffer into @buf
145  * This variant assumes that the buffer is a memory at the userspace. So,
154  * dvb_ringbuffer_read - Reads a buffer into a pointer
157  * @buf: pointer to the buffer where the data will be stored
158  * @len: bytes from ring buffer into @buf
160  * This variant assumes that the buffer is a memory at the Kernel space
172  * DVB_RINGBUFFER_WRITE_BYTE - write single byte to ring buffer
182  * dvb_ringbuffer_write - Writes a buffer into the ringbuffer
185  * @buf: pointer to the buffer where the data will be read
186  * @len: bytes from ring buffer into @buf
188  * This variant assumes that the buffer is a memory at the Kernel space
196  * dvb_ringbuffer_write_user - Writes a buffer received via a user pointer
199  * @buf: pointer to the buffer where the data will be read
200  * @len: bytes from ring buffer into @buf
202  * This variant assumes that the buffer is a memory at the userspace. So,
214  * @buf: Buffer to write.
215  * @len: Length of buffer (currently limited to 65535 bytes max).
228  * @buf: Destination buffer for data.
229  * @len: Size of destination buffer.
252  * @buf: Destination buffer for data.
253  * @len: Size of destination buffer.
261  * dvb_ringbuffer_pkt_dispose - Dispose of a packet in the ring buffer.
263  * @rbuf: Ring buffer concerned.
