From 4266129964b8238526936d723de65b419d8069c6 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 31 May 2011 16:27:44 -0300 Subject: [media] DocBook: Move all media docbook stuff into its own directory This patch addresses several issues pointed by Randy Dunlap at changeset ece722c: - In the generated index.html file, "media" is listed first, but it should be listed in alphabetical order, not first. - The generated files are (hidden) in .tmpmedia/ - The link from the top-level index.html file to "media" is to media/index.html, but the file is actually in .tmpmedia/media/index.html - Please build docs with and without using "O=builddir" and test that. - Would it be possible for media to have its own Makefile instead of merging into this one? Due to the way cleandocs target works, I had to rename the media DocBook to media_api, otherwise cleandocs would remove the /media directory.

-CA Function Calls - - -
-open() -DESCRIPTION - - -This system call opens a named ca device (e.g. /dev/ost/ca) for subsequent use. -When an open() call has succeeded, the device will be ready for use. - The significance of blocking or non-blocking mode is described in the - documentation for functions where there is a difference. It does not affect the - semantics of the open() call itself. A device opened in blocking mode can later - be put into non-blocking mode (and vice versa) using the F_SETFL command - of the fcntl system call. This is a standard system call, documented in the Linux - manual page for fcntl. Only one user can open the CA Device in O_RDWR - mode. All other attempts to open the device in this mode will fail, and an error - code will be returned. - - -SYNOPSIS - - -int open(const char ⋆deviceName, int flags); - - -PARAMETERS - - -const char - *deviceName - -Name of specific video device. - - -int flags - -A bit-wise OR of the following flags: - - - -O_RDONLY read-only access - - - -O_RDWR read/write access - - - -O_NONBLOCK open in non-blocking mode - - - -(blocking mode is the default) - - -ERRORS - - -ENODEV - -Device driver not loaded/available. - - -EINTERNAL - -Internal error. - - -EBUSY - -Device or resource busy. - - -EINVAL - -Invalid argument. - - - -

-close() -DESCRIPTION - - -This system call closes a previously opened audio device. - - -SYNOPSIS - - -int close(int fd); - - -PARAMETERS - - -int fd - -File descriptor returned by a previous call to open(). - - -ERRORS - - -EBADF - -fd is not a valid open file descriptor. - - -
