GLGETATTACHEDSHADERS(3G)					  [FIXME: manual]					  GLGETATTACHEDSHADERS(3G)

NAME

       glGetAttachedShaders - Returns the handles of the shader objects attached to a program object

C SPECIFICATION

       void glGetAttachedShaders(GLuint program, GLsizei maxCount, GLsizei *count, GLuint *shaders);

PARAMETERS

       program
	   Specifies the program object to be queried.

       maxCount
	   Specifies the size of the array for storing the returned object names.

       count
	   Returns the number of names actually returned in objects.

       shaders
	   Specifies an array that is used to return the names of attached shader objects.

DESCRIPTION

       glGetAttachedShaders returns the names of the shader objects attached to program. The names of shader objects that are attached to program
       will be returned in shaders.  The actual number of shader names written into shaders is returned in count.  If no shader objects are
       attached to program, count is set to 0. The maximum number of shader names that may be returned in shaders is specified by maxCount.

       If the number of names actually returned is not required (for instance, if it has just been obtained by calling glGetProgram()), a value of
       NULL may be passed for count. If no shader objects are attached to program, a value of 0 will be returned in count. The actual number of
       attached shaders can be obtained by calling glGetProgram() with the value GL_ATTACHED_SHADERS.

ERRORS

       GL_INVALID_VALUE is generated if program is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if program is not a program object.

       GL_INVALID_VALUE is generated if maxCount is less than 0.

ASSOCIATED GETS

       glGetProgram() with argument GL_ATTACHED_SHADERS

       glIsProgram()

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.
