NAME
       glLinkProgramARB - Links a program object.

C SPECIFICATION
       void glLinkProgramARB( GLhandleARB program )

PARAMETERS
       program Specifies the program object to be linked.

DESCRIPTION
       glLinkProgramARB links the program object specified by program.	When a
       program	object	is linked an executable is created from all the shader
       objects which are attached to the program object.  Any attached	shader
       objects	of subtype GL_VERTEX_SHADER_ARB will be used to create an exe‐
       cutable to run on the vertex processor.	Any attached shader objects of
       subtype	GL_FRAGMENT_SHADER_ARB will be used to create an executable to
       run on the fragment processor.

       The status of a link operation can be queried by calling glGetObjectPa‐
       rameterARB with arguments program and GL_OBJECT_LINK_STATUS_ARB. If the
       link was successful the status will be  GL_TRUE	otherwise  the	status
       will be GL_FALSE.

       When  a	program	 object	 has been successfully linked all active user-
       defined uniform variables belonging to program will be initialized to 0
       and  all the program object's active uniform variables will be assigned
       locations.  These locations  can be queried by calling  glGetUniformLo‐
       cationARB.

       Information  about  the link operation can be queried by calling glGet‐
       InfoLogARB.

       If a program object only has  vertex  shaders  attached	they  will  be
       linked with the fixed function fragment processing. Similarly if a pro‐
       gram object only has fragment shaders attached they will be linked with
       the fixed function vertex processing.

NOTES
       glLinkProgramARB can return before the link operation has completed.

ERRORS
       GL_INVALID_VALUE	 is  generated	if  program  is	  not  a valid program
       object.

       GL_INVALID_OPERATION is generated if program is	not  of	 type  GL_PRO‐
       GRAM_OBJECT_ARB.

       GL_INVALID_ENUM is generated if pname is not an accepted value.

       GL_INVALID_OPERATION  is generated glLinkProgramARB is executed between
       the execution of glBegin and the corresponding execution of glEnd.
