dag(4)

NAME
dag - Endace DAG card device

DESCRIPTION
/dev/dag0, /dev/dag1, /dev/dag2 are character devices representing the first, second, third etc. DAG cards detected by the operating system.

The device nodes serve to link an open(2) call to the DAG device driver. For DAG API clients it is sufficient to pass the name of the desired device node to the dag_open(3) routine and use the DAG API to capture and transmit packets.

Operations:

read
    Reads from the DAG card's memory buffer.

write
    Writes to the DAG card's memory buffer.

mmap
    Maps the DAG card's memory buffer into a process' virtual address space. Unlike the DAG API call dag_mmap(3), this results in a single mapping of the buffer.

FILES
/dev/dag0, /dev/dag1, /dev/dag2, ...
