[FIXME: source]                                    11/18/2024                                    GLGETSHADER(3G)

glGetShader returns in params the value of a parameter for a specific shader object. The following
       parameters are defined:

       GL_SHADER_TYPEparams returns GL_VERTEX_SHADER if shader is a vertex shader object, GL_GEOMETRY_SHADER if shader is
           a geometry shader object, and GL_FRAGMENT_SHADER if shader is a fragment shader object.

       GL_DELETE_STATUSparams returns GL_TRUE if shader is currently flagged for deletion, and GL_FALSE otherwise.

       GL_COMPILE_STATUSparams returns GL_TRUE if the last compile operation on shader was successful, and GL_FALSE
           otherwise.

       GL_INFO_LOG_LENGTHparams returns the number of characters in the information log for shader including the null
           termination character (i.e., the size of the character buffer required to store the information log).
           If shader has no information log, a value of 0 is returned.

       GL_SHADER_SOURCE_LENGTHparams returns the length of the concatenation of the source strings that make up the shader source
           for the shader, including the null termination character. (i.e., the size of the character buffer
           required to store the shader source). If no source code exists, 0 is returned.

GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if shader does not refer to a shader object.

       GL_INVALID_ENUM is generated if pname is not an accepted value.

       If an error is generated, no change is made to the contents of params.

shader
           Specifies the shader object to be queried.

       pname
           Specifies the object parameter. Accepted symbolic names are GL_SHADER_TYPE, GL_DELETE_STATUS,
           GL_COMPILE_STATUS, GL_INFO_LOG_LENGTH, GL_SHADER_SOURCE_LENGTH.

       params
           Returns the requested object parameter.
