NAME

       glCreateShader - Creates a shader object

C SPECIFICATION

       GLuint glCreateShader(GLenum shaderType);

PARAMETERS

       shaderType
           Specifies the type of shader to be created. Must be one of GL_COMPUTE_SHADER,
           GL_VERTEX_SHADER, GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER,
           GL_GEOMETRY_SHADER, or GL_FRAGMENT_SHADER.

DESCRIPTION

       glCreateShader creates an empty shader object and returns a non-zero value by which it can
       be referenced. A shader object is used to maintain the source code strings that define a
       shader.  shaderType indicates the type of shader to be created. Five types of shader are
       supported. A shader of type GL_COMPUTE_SHADER is a shader that is intended to run on the
       programmable compute processor. A shader of type GL_VERTEX_SHADER is a shader that is
       intended to run on the programmable vertex processor. A shader of type
       GL_TESS_CONTROL_SHADER is a shader that is intended to run on the programmable
       tessellation processor in the control stage. A shader of type GL_TESS_EVALUATION_SHADER is
       a shader that is intended to run on the programmable tessellation processor in the
       evaluation stage. A shader of type GL_GEOMETRY_SHADER is a shader that is intended to run
       on the programmable geometry processor. A shader of type GL_FRAGMENT_SHADER is a shader
       that is intended to run on the programmable fragment processor.

       When created, a shader object's GL_SHADER_TYPE parameter is set to either
       GL_COMPUTE_SHADER, GL_VERTEX_SHADER, GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER,
       GL_GEOMETRY_SHADER or GL_FRAGMENT_SHADER, depending on the value of shaderType.

NOTES

       Like buffer and texture objects, the name space for shader objects may be shared across a
       set of contexts, as long as the server sides of the contexts share the same address space.
       If the name space is shared across contexts, any attached objects and the data associated
       with those attached objects are shared as well.

       Applications are responsible for providing the synchronization across API calls when
       objects are accessed from different execution threads.

       GL_COMPUTE_SHADER is available only if the GL version is 4.3 or higher.

ERRORS

       This function returns 0 if an error occurs creating the shader object.

       GL_INVALID_ENUM is generated if shaderType is not an accepted value.
