NAME
       glCreateProgram - Creates a program object

C SPECIFICATION
       GLuint glCreateProgram(void);

DESCRIPTION
       glCreateProgram creates an empty program object and returns a non-zero value by which it
       can be referenced. A program object is an object to which shader objects can be attached.
       This provides a mechanism to specify the shader objects that will be linked to create a
       program. It also provides a means for checking the compatibility of the shaders that will
       be used to create a program (for instance, checking the compatibility between a vertex
       shader and a fragment shader). When no longer needed as part of a program object, shader
       objects can be detached.

       One or more executables are created in a program object by successfully attaching shader
       objects to it with glAttachShader(), successfully compiling the shader objects with
       glCompileShader(), and successfully linking the program object with glLinkProgram(). These
       executables are made part of current state when glUseProgram() is called. Program objects
       can be deleted by calling glDeleteProgram(). The memory associated with the program object
       will be deleted when it is no longer part of current rendering state for any context.

NOTES
       Like buffer and texture objects, the name space for program objects may be shared across a
       set of contexts, as long as the server sides of the contexts share the same address space.
       If the name space is shared across contexts, any attached objects and the data associated
       with those attached objects are shared as well.

       Applications are responsible for providing the synchronization across API calls when
       objects are accessed from different execution threads.

ERRORS
       This function returns 0 if an error occurs creating the program object.
