NAME

       glAttachShader - Attaches a shader object to a program object

C SPECIFICATION

       void glAttachShader(GLuint program, GLuint shader);

PARAMETERS

       program
           Specifies the program object to which a shader object will be attached.

       shader
           Specifies the shader object that is to be attached.

DESCRIPTION

       In order to create a complete shader program, there must be a way to specify the list of things that will
       be linked together. Program objects provide this mechanism. Shaders that are to be linked together in a
       program object must first be attached to that program object.  glAttachShader attaches the shader object
       specified by shader to the program object specified by program. This indicates that shader will be
       included in link operations that will be performed on program.

       All operations that can be performed on a shader object are valid whether or not the shader object is
       attached to a program object. It is permissible to attach a shader object to a program object before
       source code has been loaded into the shader object or before the shader object has been compiled. It is
       permissible to attach multiple shader objects of the same type because each may contain a portion of the
       complete shader. It is also permissible to attach a shader object to more than one program object. If a
       shader object is deleted while it is attached to a program object, it will be flagged for deletion, and
       deletion will not occur until glDetachShader() is called to detach it from all program objects to which
       it is attached.

ERRORS

       GL_INVALID_VALUE is generated if either program or shader is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if program is not a program object.

       GL_INVALID_OPERATION is generated if shader is not a shader object.

       GL_INVALID_OPERATION is generated if shader is already attached to program.

ASSOCIATED GETS

       glGetShaderInfoLog()

       glGetShaderSource()
