NAME
       glBindVertexBuffers, glVertexArrayVertexBuffers - attach multiple buffer objects to a vertex array object


C SPECIFICATION
       void glBindVertexBuffers(GLuint first, GLsizei count, const GLuint *buffers, const GLuintptr *offsets,
                                const GLsizei *strides);

       void glVertexArrayVertexBuffers(GLuint vaobj, GLuint first, GLsizei count, const GLuint *buffers,
                                       const GLintptr *offsets, const GLsizei *strides);


PARAMETERS
       vaobj
           Specifies the name of the vertex array object for glVertexArrayVertexBuffers.

       first
           Specifies the first vertex buffer binding point to which a buffer object is to be bound.

       count
           Specifies the number of buffers to bind.

       buffers
           Specifies the address of an array of names of existing buffer objects.

       offsets
           Specifies the address of an array of offsets to associate with the binding points.

       buffers
           Specifies the address of an array of strides to associate with the binding points.


DESCRIPTION
       glBindVertexBuffers and glVertexArrayVertexBuffers bind storage from an array of existing buffer objects
       to a specified number of consecutive vertex buffer binding points units in a vertex array object. For
       glBindVertexBuffers, the vertex array object is the currently bound vertex array object. For
       glVertexArrayVertexBuffers, vaobj is the name of the vertex array object.

       count existing buffer objects are bound to vertex buffer binding points numbered $first$ through $first +
       count - 1$. If buffers is not NULL, it specifies an array of count values, each of which must be zero or
       the name of an existing buffer object.  offsets and strides specify arrays of count values indicating the
       offset of the first element and stride between elements in each buffer, respectively. If buffers is NULL,
       each affected vertex buffer binding point from $first$ through $first + count - 1$ will be reset to have
       no bound buffer object. In this case, the offsets and strides associated with the binding points are set
       to default values, ignoring offsets and strides.

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

               for (i = 0; i < count; i++) {
                   if (buffers == NULL) {
                       glBindVertexBuffer(first + i, 0, 0, 16);
                   } else {
                       glBindVertexBuffer(first + i, buffers[i], offsets[i], strides[i]);
                   }
               }

       except that buffers will not be created if they do not exist.

       glVertexArrayVertexBuffers is equivalent to the pseudocode above, but replacing glBindVertexBuffers(args)
       with glVertexArrayVertexBuffers(vaobj, args).

       The values specified in buffers, offsets, and strides will be checked separately for each vertex buffer
       binding point. When a value for a specific vertex buffer binding point is invalid, the state for that
       binding point will be unchanged and an error will be generated. However, state for other vertex buffer
       binding points will still be changed if their corresponding values are valid.


ERRORS
       GL_INVALID_OPERATION is generated by glBindVertexBuffers if no vertex array object is bound.

       GL_INVALID_OPERATION is generated by glVertexArrayVertexBuffers if vaobj is not the name of the vertex
       array object.

       GL_INVALID_OPERATION is generated if $first + count$ is greater than the value of
       GL_MAX_VERTEX_ATTRIB_BINDINGS.

       GL_INVALID_OPERATION is generated if any value in buffers is not zero or the name of an existing buffer
       object.

       GL_INVALID_VALUE is generated if any value in offsets or strides is negative, or if a value is stride is
       greater than the value of GL_MAX_VERTEX_ATTRIB_STRIDE.
