NAME

       glGetQueryIndexediv - return parameters of an indexed query object target

C SPECIFICATION

       void glGetQueryIndexediv(GLenum target, GLuint index, GLenum pname, GLint * params);

PARAMETERS

       target
	   Specifies a query object target. Must be GL_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED, 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.

DESCRIPTION

       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.

NOTES

       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.

ERRORS

       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.

NAME

       glGetQueryObject - return parameters of a query object

C SPECIFICATION

       void glGetQueryObjectiv(GLuint id, GLenum pname, GLint * params);

       void glGetQueryObjectuiv(GLuint id, GLenum pname, GLuint * params);

       void glGetQueryObjecti64v(GLuint id, GLenum pname, GLint64 * params);

       void glGetQueryObjectui64v(GLuint id, GLenum pname, GLuint64 * params);

PARAMETERS

       id
	   Specifies the name of a query object.

       pname
	   Specifies the symbolic name of a query object parameter. Accepted values are GL_QUERY_RESULT or GL_QUERY_RESULT_AVAILABLE.

       params
	   Returns the requested data.

DESCRIPTION

       glGetQueryObject returns in params a selected parameter of the query object specified by id.

       pname names a specific query object parameter.  pname can be as follows:

       GL_QUERY_RESULT
	   params returns the value of the query object's passed samples counter. The initial value is 0.

       GL_QUERY_RESULT_AVAILABLE
	   params returns whether the passed samples counter is immediately available. If a delay would occur waiting for the query result,
	   GL_FALSE is returned. Otherwise, GL_TRUE is returned, which also indicates that the results of all previous queries are available as
	   well.

NOTES

       If an error is generated, no change is made to the contents of params.

       glGetQueryObject implicitly flushes the GL pipeline so that any incomplete rendering delimited by the occlusion query completes in finite
       time.

       If multiple queries are issued using the same query object id before calling glGetQueryObject, the results of the most recent query will be
       returned. In this case, when issuing a new query, the results of the previous query are discarded.

       glGetQueryObjecti64v and glGetQueryObjectui64v are available only if the GL version is 3.3 or greater.

ERRORS

       GL_INVALID_ENUM is generated if pname is not an accepted value.

       GL_INVALID_OPERATION is generated if id is not the name of a query object.

       GL_INVALID_OPERATION is generated if id is the name of a currently active query object.
