The EGL_CLIENT_APIS string describes which client rendering APIs are

320 |
supported. It is zero-terminated and contains a space-separated list of API

321 |
names, which must include at least one of ‘‘OpenGL’’, ‘‘OpenGL_ES’’ or

|
|
322 |
‘‘OpenVG’’.

The EGL_EXTENSIONS string describes which EGL extensions are supported
|

324 |
by the EGL implementation running on the specified display. The string is zeroterminated
|
|
|
325 |
and contains a space-separated list of extension names; extension names

326 |
themselves do not contain spaces. If there are no extensions to EGL, then the empty

328 |
The format and contents of the EGL_VENDOR string is implementation dependent.
