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()
