gluCheckExtension - determines if an extension name is supported
GLboolean gluCheckExtension( | const GLubyte* | extName, |
const GLubyte* | extString) ; |
extName
Specifies an extension name.
extString
Specifies a space-separated list of extension names supported.
gluCheckExtension
returns GLU_TRUE
if extName
is supported otherwise
GLU_FALSE
is returned.
This is used to check for the presence for OpenGL ES, GLU ES or EGL by passing the extension strings returned by glGetString
,
gluGetString or eglQueryString
respectively, as extString
.
Cases where one extension name is a substring of another are correctly handled.
There may or may not be leading or trailing blanks in extString
.
Extension names should not contain embedded spaces.
All strings are null-terminated.
