NAME
       glGetShaderSource - Returns the source code string from a shader object

C SPECIFICATION
       void glGetShaderSource(GLuint shader, GLsizei bufSize, GLsizei *length, GLchar *source);

PARAMETERS
       shader
	   Specifies the shader object to be queried.

       bufSize
	   Specifies the size of the character buffer for storing the returned source code
	   string.

       length
	   Returns the length of the string returned in source (excluding the null terminator).

       source
	   Specifies an array of characters that is used to return the source code string.

DESCRIPTION
       glGetShaderSource returns the concatenation of the source code strings from the shader
       object specified by shader. The source code strings for a shader object are the result of
       a previous call to glShaderSource(). The string returned by the function will be null
       terminated.

       glGetShaderSource returns in source as much of the source code string as it can, up to a
       maximum of bufSize characters. The number of characters actually returned, excluding the
       null termination character, is specified by length. If the length of the returned string
       is not required, a value of NULL can be passed in the length argument. The size of the
       buffer required to store the returned source code string can be obtained by calling
       glGetShader() with the value GL_SHADER_SOURCE_LENGTH.

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

       GL_INVALID_OPERATION is generated if shader is not a shader object.

       GL_INVALID_VALUE is generated if bufSize is less than 0.

ASSOCIATED GETS
       glGetShader() with argument GL_SHADER_SOURCE_LENGTH

       glIsShader()
