dvb_ringbuffer_pkt_read(9)

dvb_ringbuffer_pkt_read(9) 💅

okay so bestie, welcome to the Kernel API Manual — today's main character is dvb_ringbuffer_pkt_read, and she is literally here to read from a packet in the ringbuffer. no cap. 🦋

NAME ✨

dvb_ringbuffer_pkt_read — Read from a packet in the ringbuffer.

SYNOPSIS 🎀

ssize_t dvb_ringbuffer_pkt_read (struct dvb_ringbuffer *rbuf , size_t idx , int offset , u8 *buf , size_t len );

ARGUMENTS 🌸

• rbuf — the ringbuffer concerned. 💖
• idx — packet index as returned by dvb_ringbuffer_pkt_next.
• offset — offset into the packet to read from.
• buf — destination buffer for the data.
• len — size of the destination buffer.

NOTE 💀

okay important, bestie: unlike dvb_ringbuffer_read_user, this DOES update the read pointer in the ringbuffer. it's giving “yes, actually updates it” energy. periodt.

RETURN 🔥

Number of bytes read, or -EFAULT.
