glGetQueryIndexediv — return parameters of an indexed query object target
void glGetQueryIndexediv( | GLenum | target, |
GLuint | index, | |
GLenum | pname, | |
GLint * | params) ; |
target
Specifies a query object target.
Must be GL_SAMPLES_PASSED
, GL_ANY_SAMPLES_PASSED
, GL_ANY_SAMPLES_PASSED_CONSERVATIVE
GL_PRIMITIVES_GENERATED
, GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN
,
GL_TIME_ELAPSED
, or GL_TIMESTAMP
.
index
Specifies the index of the query object target.
pname
Specifies the symbolic name of a query object target parameter.
Accepted values are GL_CURRENT_QUERY
or GL_QUERY_COUNTER_BITS
.
params
Returns the requested data.
glGetQueryIndexediv
returns in params
a selected parameter of the indexed query object target
specified by target
and index
. index
specifies the index of the
query object target and must be between zero and a target-specific maxiumum.
pname
names a specific query object target parameter. When pname
is
GL_CURRENT_QUERY
, the name of the currently active query for the specified index
of target
,
or zero if no query is active, will be placed in params
.
If pname
is GL_QUERY_COUNTER_BITS
, the implementation-dependent number
of bits used to hold the result of queries for target
is returned in params
.
The target GL_ANY_SAMPLES_PASSED_CONSERVATIVE
is available only if the GL version is 4.3 or greater.
If an error is generated,
no change is made to the contents of params
.
Calling glGetQueryiv is equivalent to calling
glGetQueryIndexediv
with index
set to zero.
GL_INVALID_ENUM
is generated if target
or pname
is not an
accepted value.
GL_INVALID_VALUE
is generated if index
is greater than or equal to the
target
-specific maximum.
