.SH "PARAMETERS"
.PP
\fItarget\fR
.RS 4
Specifies a query object target\&. Must be
\fBGL_SAMPLES_PASSED\fR,
\fBGL_ANY_SAMPLES_PASSED\fR,
\fBGL_ANY_SAMPLES_PASSED_CONSERVATIVE\fR
\fBGL_PRIMITIVES_GENERATED\fR,
\fBGL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN\fR,
\fBGL_TIME_ELAPSED\fR, or
\fBGL_TIMESTAMP\fR\&.
.RE
.PP
\fIpname\fR
.RS 4
Specifies the symbolic name of a query object target parameter\&. Accepted values are
\fBGL_CURRENT_QUERY\fR
or
\fBGL_QUERY_COUNTER_BITS\fR\&.

.SH "DESCRIPTION"
.PP
\fBglGetQueryiv\fR
returns in
\fIparams\fR
a selected parameter of the query object target specified by
\fItarget\fR\&.
.PP
\fIpname\fR
names a specific query object target parameter\&. When
\fIpname\fR
is
\fBGL_CURRENT_QUERY\fR, the name of the currently active query for
\fItarget\fR, or zero if no query is active, will be placed in
\fIparams\fR\&. If
\fIpname\fR
is
\fBGL_QUERY_COUNTER_BITS\fR, the implementation\-dependent number of bits used to hold the result of queries for
\fItarget\fR
is returned in
\fIparams\fR\&.
.SH "NOTES"
.PP
The target
\fBGL_ANY_SAMPLES_PASSED_CONSERVATIVE\fR
is available only if the GL version is 4\&.3 or greater\&.
.PP
If an error is generated, no change is made to the contents of
\fIparams\fR\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_ENUM\fR
is generated if
