The VThe V-Ray OSL Texture TexOSL map can be used to load Open Shading Language OSL shader code files (.osl) or OSL object OSL object code files (.oso) and render them directly with V-Ray. It can be used with shaders that have simple color and float output parameters. These parameters are considered respectively as texture RGB and alpha outputs.

If the shader file describes a material (rather than a texture) and writes its result in an output closure color parameter, it is advised to use the V-Ray OSL Material. Otherwise, the texture map will not evaluate the materials and would will be rendered black.

For more on OSL in general, see the Github reference.
