void glfShaderProgram::AttachShader ( const glfShader & shader )

Attaches a shader to the program.

Must be called after glfShaderProgram::Create and before glfShaderProgram::Link.

void glfShaderProgram::AttachShaderFromFile	(	GLenum	type,
		const std::string &	fileName
	)

Attaches a shader to the program, without the need to create an instance of the glfShader class.

The source code of the shader is loaded from a file.

Parameters

type	Either GL_VERTEX_SHADER or GL_FRAGMENT_SHADER.
fileName	Name of file to load the GLSL source from.

void glfShaderProgram::AttachShaderFromSource	(	GLenum	type,
		const std::string &	sourceCode
	)

Attaches a shader to the program, without the need to create an instance of the glfShader class.

Parameters

type	Either GL_VERTEX_SHADER or GL_FRAGMENT_SHADER.
sourceCode	The GLSL source code.

string glfShaderProgram::GetInfoLog ( ) const

Returns the info log containing information about the linking of the shader program.

Note: If linking the shader programs fails, the info log is also contained in the message of the thrown exception.
