glGetQueryiv — return parameters of a query object target
void glGetQueryiv(
|
GLenum target, |
| 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.
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.
glGetQueryiv returns in params a selected parameter of the query object target
specified by target.
pname names a specific query object target parameter. When pname is
GL_CURRENT_QUERY, the name of the currently active query for 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.
GL_INVALID_ENUM is generated if target or pname is not an
accepted value.
