unit
sampler
glBindSampler binds sampler to the texture unit at index unit. sampler must be zero or the name of a sampler object previously returned from a call to glGenSamplers(). unit must be less than the value of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
When a sampler object is bound to a texture unit, its state supersedes that of the texture object bound to that texture unit. If the sampler name zero is bound to a texture unit, the currently bound texture's sampler state becomes active. A single sampler object may be bound to multiple texture units simultaneously.
glBindSampler is available only if the GL version is 3.3 or higher.
GL_INVALID_VALUE is generated if unit is greater than or equal to the value of GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS.
GL_INVALID_OPERATION is generated if sampler is not zero or a name previously returned from a call to glGenSamplers(), or if such a name has been deleted by a call to glDeleteSamplers().
