+.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.
