getting versions

Pswin · August 27, 2009, 3:41pm

hi

i can get OpenGL version name by

glGetString(GL_VERSION);

and i can get OpenGL major and minor version by:

glGetIntegerv(GL_MAJOR_VERSION, &major); 
glGetIntegerv(GL_MINOR_VERSION, &minor);

but how can i get GLSL version? (with out using glGetString)
and how can i get shader model??

Though integer major/minor queries would be nice to have, since the GLSL version string format is standard, just sscanf it. Not ideal but should be guaranteed to work:

glGetString:

The GL_VERSION and GL_SHADING_LANGUAGE_VERSION strings begin with a version number. The version number uses one of these forms:
        major_number.minor_number
        major_number.minor_number.release_number

However glGetString is deprecated. I guest the GLSL version depend on the OpenGL version. That’s actually what I assume but am I right to do that?

glGetString is not deprecated.
Only GL_EXTENSIONS enum value for its argument is deprecated.

I feel it is going to take a while until I figure out all details about what is deprecated or not …

I know that feeling.

It’s as simple as reading the quick reference. glGetString is black, hence not deprecated. Indeed, it specifically says under it that using GL_EXTENSIONS in it is deprecated.
