The access output provides the lowest level of access in a VLC chain; see also [[Documentation:Hacker's Guide/Access]]. It provides minimaly a Write() interface expecting a buffer block to be written to the underlying media.

= Usage =

As the name suggests, these modules are designed to be the first and last elements of a modules chain. Access [[Documentation:Hacker's Guide/Access|input]] and [[Documentation:Hacker's Guide/Access output|output]] handles most of the basic I/O for VLC. Protocol implementations, device access (like V4L2), file access and network I/O are all examples of access modules.

= Functionnality =

Generally speaking, [[Documentation:Hacker's Guide/Access|access input]] will provide Read() functions and [[Documentation:Hacker's Guide/Access output|output]] Write(). Both needs to provide Seek() and Control() even if the underlying architecture does not support these actions. In this case, Seek() and Control() should return VLC_EGENERIC, althout Control() might need to answer ACCESS_OUT_CONTROLS_PACE requests. See modules/acces_output/http.c about using a source without seeking.
