GLGETBUFFERPOINTERV(3G)                          OpenGL 3.3                          GLGETBUFFERPOINTERV(3G)



NAME
       glGetBufferPointerv - return the pointer to a mapped buffer object's data store

C SPECIFICATION
       void glGetBufferPointerv(GLenum target, GLenum pname, GLvoid ** params);

PARAMETERS
       target
           Specifies the target buffer object. The symbolic constant must be GL_ARRAY_BUFFER,
           GL_COPY_READ_BUFFER, GL_COPY_WRITE_BUFFER, GL_ELEMENT_ARRAY_BUFFER, GL_PIXEL_PACK_BUFFER,
           GL_PIXEL_UNPACK_BUFFER, GL_TEXTURE_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER, or GL_UNIFORM_BUFFER.

       pname
           Specifies the pointer to be returned. The symbolic constant must be GL_BUFFER_MAP_POINTER.

       params
           Returns the pointer value specified by pname.

DESCRIPTION
       glGetBufferPointerv returns pointer information.  pname is a symbolic constant indicating the pointer
       to be returned, which must be GL_BUFFER_MAP_POINTER, the pointer to which the buffer object's data
       store is mapped. If the data store is not currently mapped, NULL is returned.  params is a pointer to
       a location in which to place the returned pointer value.

NOTES
       If an error is generated, no change is made to the contents of params.

       The initial value for the pointer is NULL.

ERRORS
       GL_INVALID_ENUM is generated if target or pname is not an accepted value.


       GL_INVALID_OPERATION is generated if the reserved buffer object name 0 is bound to target.
