I stumbled across a somewhat strange behavior of tar and find no explanation for it: i was testing a DVD for read errors and thought to simply tar the content and direct the output to /dev/null:
tar -cvf - /my/mountpoint/*ts > /dev/null
This way i expected the system to read the complete... (4 Replies)
Hi,
We have a website running on a local centos 5.4 surfer, static IP.
The domain.com uses no-ip.com to take care of the DNS, it forwards all to my server.
My router receives the port 80 call, routes it to my server and the world can see domain.com perfectly fine.
However, we cannot see... (3 Replies)

GLXCREATECONTEXT() GLXCREATECONTEXT()
NAME
glXCreateContext - create a new GLX rendering context
C SPECIFICATION
GLXContext glXCreateContext( Display *dpy,
XVisualInfo *vis,
GLXContext shareList,
Bool direct )
delim $$
PARAMETERS
dpy Specifies the connection to the X server.
vis Specifies the visual that defines the frame buffer resources available to the rendering context. It is a pointer to an XVisual-
Info structure, not a visual ID or a pointer to a Visual.
shareList Specifies the context with which to share display lists. NULL indicates that no sharing is to take place.
direct Specifies whether rendering is to be done with a direct connection to the graphics system if possible (True) or through the X
server (False).
DESCRIPTION
glXCreateContext creates a GLX rendering context and returns its handle. This context can be used to render into both windows and GLX
pixmaps. If glXCreateContext fails to create a rendering context, NULL is returned.
If direct is True, then a direct rendering context is created if the implementation supports direct rendering, if the connection is to an X
server that is local, and if a direct rendering context is available. (An implementation may return an indirect context when direct is
True). If direct is False, then a rendering context that renders through the X server is always created. Direct rendering provides a per-
formance advantage in some implementations. However, direct rendering contexts cannot be shared outside a single process, and they may be
unable to render to GLX pixmaps.
If shareList is not NULL, then all display-list indexes and definitions are shared by context shareList and by the newly created context.
An arbitrary number of contexts can share a single display-list space. However, all rendering contexts that share a single display-list
space must themselves exist in the same address space. Two rendering contexts share an address space if both are nondirect using the same
server, or if both are direct and owned by a single process. Note that in the nondirect case, it is not necessary for the calling threads
to share an address space, only for their related rendering contexts to share an address space.
If the GL version is 1.1 or greater, then all texture objects except object 0, are shared by any contexts that share display lists.
NOTES
XVisualInfo is defined in Xutil.h. It is a structure that includes visual, visualID, screen, and depth elements.
A process is a single execution environment, implemented in a single address space, consisting of one or more threads.
A thread is one of a set of subprocesses that share a single address space, but maintain separate program counters, stack spaces, and other
related global data. A thread that is the only member of its subprocess group is equivalent to a process.
It may not be possible to render to a GLX pixmap with a direct rendering context.
ERRORS
NULL is returned if execution fails on the client side.
BadMatch is generated if the context to be created would not share the address space or the screen of the context specified by shareList.
BadValue is generated if vis is not a valid visual (for example, if a particular GLX implementation does not support it).
GLXBadContext is generated if shareList is not a GLX context and is not NULL.
BadAlloc is generated if the server does not have enough resources to allocate the new context.
