glutExtensionSupported(3GLUT) GLUT glutExtensionSupported(3GLUT)NAME
glutExtensionSupported - helps to easily determine whether a given OpenGL extension is supported.
SYNTAX
#include <GLUT/glut.h>
int glutExtensionSupported(char *extension);
ARGUMENTS
extension Name of OpenGL extension.
DESCRIPTION
glutExtensionSupported helps to easily determine whether a given OpenGL extension is supported or not. The extension parameter names the
extension to query. The supported extensions can also be determined with glGetString(GL_EXTENSIONS), but glutExtensionSupported does the
correct parsing of the returned string.
glutExtensionSupported returns non-zero if the extension is supported, zero if not supported.
There must be a valid current window to call glutExtensionSupported.
glutExtensionSupported only returns information about OpenGL extensions only. This means window system dependent extensions (for example,
GLX extensions) are not reported by glutExtensionSupported.
EXAMPLE
Here is an example of using glutExtensionSupported:
if (!glutExtensionSupported("GL_EXT_texture")) {
fprintf(stderr, "Missing the texture extension!
");
exit(1);
}
Notice that the name argument includes both the GL prefix and the extension family prefix (EXT).
SEE ALSO
glutGet, glGetString

How do you write a shell script that change the extension of all the files?
e.g
chext rtf doc
where .rtf is the original extension
and .doc is the new extension
is it something to do with basename?

Can anyone tell me the easiest way to append an extension (ie. .ldr) to all files in a directory that do NOT have an extension? The directory contains files with and without extensions, however I'm only interested in the files with NO extension.
