NAME

       glCreateShaderProgramv - create a stand-alone program from an array of null-terminated source code strings

C SPECIFICATION

       GLuint glCreateShaderProgramv(GLenum type, GLsizei count, const char **strings);

PARAMETERS

       type
	   Specifies the type of shader to create.

       count
	   Specifies the number of source code strings in the array strings.

       strings
	   Specifies the address of an array of pointers to source code strings from which to create the program object.

DESCRIPTION

       glCreateShaderProgram creates a program object containing compiled and linked shaders for a single stage specified by type.  strings refers
       to an array of count strings from which to create the shader executables.

       glCreateShaderProgram is equivalent (assuming no errors are generated) to:

	       const GLuint shader = glCreateShader(type);
	       if (shader) {
		   glShaderSource(shader, count, strings, NULL);
		   glCompileShader(shader);
		   const GLuint program = glCreateProgram();
		   if (program) {
		       GLint compiled = GL_FALSE;
		       glGetShaderiv(shader, GL_COMPILE_STATUS, &compiled);
		       glProgramParameteri(program, GL_PROGRAM_SEPARABLE, GL_TRUE);
		       if (compiled) {
			   glAttachShader(program, shader);
			   glLinkProgram(program);
			   glDetachShader(program, shader);
		       }
		       /* append-shader-info-log-to-program-info-log */
		   }
		   glDeleteShader(shader);
		   return program;
	       } else {
		   return 0;
	       }

       The program object created by glCreateShaderProgram has its GL_PROGRAM_SEPARABLE status set to GL_TRUE.

ERRORS

       GL_INVALID_ENUM is generated if if type is not an accepted shader type.

       GL_INVALID_VALUE is generated if count is negative.

       Other errors are generated if the supplied shader code fails to compile and link, as described for the commands in the pseudocode sequence
       above, but all such errors are generated without any side effects of executing those commands.

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.
