GLCREATESHADER(3G)                               OpenGL 3.3                               GLCREATESHADER(3G)



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_VERTEX_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. Three types of shaders are supported. 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_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_VERTEX_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.

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.

ASSOCIATED GETS
       glGetShader() with a valid shader object and the parameter to be queried

       glGetShaderInfoLog() with a valid shader object

       glGetShaderSource() with a valid shader object
