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.
