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.
