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

NAME

       glShaderSource - Replaces the source code in a shader object

C SPECIFICATION

       void glShaderSource(GLuint shader, GLsizei count, const GLchar **string, const GLint *length);

PARAMETERS

       shader
	   Specifies the handle of the shader object whose source code is to be replaced.

       count
	   Specifies the number of elements in the string and length arrays.

       string
	   Specifies an array of pointers to strings containing the source code to be loaded into the shader.

       length
	   Specifies an array of string lengths.

DESCRIPTION

       glShaderSource sets the source code in shader to the source code in the array of strings specified by string. Any source code previously
       stored in the shader object is completely replaced. The number of strings in the array is specified by count. If length is NULL, each
       string is assumed to be null terminated. If length is a value other than NULL, it points to an array containing a string length for each of
       the corresponding elements of string. Each element in the length array may contain the length of the corresponding string (the null
       character is not counted as part of the string length) or a value less than 0 to indicate that the string is null terminated. The source
       code strings are not scanned or parsed at this time; they are simply copied into the specified shader object.

NOTES

       OpenGL copies the shader source code strings when glShaderSource is called, so an application may free its copy of the source code strings
       immediately after the function returns.

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 count is less than 0.

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.
