GL_TEXTURE_SAMPLES in GLSL?

[JoshKlint]

Is there any GLSL function that can retrieve the number of texture samples in a sampler2DMS object?

[carsten_neumann]

Sounds like this fits the bill:

@https://registry.khronos.org/OpenGL/specs/gl/GLSLangSpec.4.60.pdf page 181

int textureSamples(gsampler2DMS sampler)
int textureSamples(gsampler2DMSArraysampler)

Returns the number of samples of the texture or textures bound to sampler
