  .TP
  \f2params\fP
  Returns the pointer value specified by \f2pname\fP.
  .SH DESCRIPTION
  \%\f3glGetPointerv\fP returns pointer information. \f2pname\fP 
  is a symbolic constant indicating the pointer to be returned, and
  \f2params\fP is a pointer to a location in which to place the returned data. 
  .SH NOTES
  \%\f3glGetPointerv\fP is available only if the GL version is 1.1 or greater.
  .P
  The pointers are all client-side state.
  .P
  The initial value for each pointer is 0. 
  .P
  When the \%\f3GL_ARB_multitexture\fP extension is supported, querying the
  \%\f3GL_TEXTURE_COORD_ARRAY_POINTER\fP returns the value for the active
  client texture unit.
  .SH ERRORS
  \%\f3GL_INVALID_ENUM\fP is generated if \f2pname\fP is not an accepted value.
