       ivec3 textureSize(gsampler2DMSArray sampler);

PARAMETERS

       sampler
           Specifies the sampler to which the texture whose dimensions to retrieve is bound.

       lod
           Specifies the level of the texture for which to retrieve the dimensions.

DESCRIPTION

       textureSize returns the dimensions of level lod (if present) of the texture bound to
       sampler. The components in the return value are filled in, in order, with the width,
       height and depth of the texture. For the array forms, the last component of the return
       value is the number of layers in the texture array.
