NAME
textureQueryLevels - compute the number of accessible mipmap levels of a texture
DECLARATION
int textureQueryLevels(gsampler1D sampler);
int textureQueryLevels(gsampler2D sampler);
int textureQueryLevels(gsampler3D sampler);
int textureQueryLevels(gsamplerCube sampler);
int textureQueryLevels(gsampler1DArray sampler);

int textureQueryLevels(sampler1DArrayShadow sampler);
int textureQueryLevels(sampler2DArrayShadow sampler);
int textureQueryLevels(samplerCubeArrayShadow sampler);
PARAMETERS
sampler
DESCRIPTION
textureQueryLevels returns the number of accessible mipmap levels in the texture associated with sampler.
If called on an incomplete texture, or if no texture is associated with sampler, zero is returned.
