GLGETSHADERSOURCE(3G)		 OpenGL Manual		 GLGETSHADERSOURCE(3G)

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()
