.SH PARAMETERS

\f2pname\fP
Specifies the array or buffer pointer to be returned.
Symbolic constants
\%\f3GL_COLOR_ARRAY_POINTER\fP,
\%\f3GL_EDGE_FLAG_ARRAY_POINTER\fP,
\%\f3GL_FEEDBACK_BUFFER_POINTER\fP,
\%\f3GL_INDEX_ARRAY_POINTER\fP,

\%\f3GL_TEXTURE_COORD_ARRAY_POINTER\fP,
\%\f3GL_SELECTION_BUFFER_POINTER\fP,
and
\%\f3GL_VERTEX_ARRAY_POINTER\fP
are accepted. 
.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.
