       var
	   parameter to retrieve

NAME

       glGetQueryiv - return parameters of a query object target

C SPECIFICATION

       void glGetQueryiv(GLenum target, GLenum pname, GLint * params);

PARAMETERS

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

DESCRIPTION

       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.

NOTES

       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.

ERRORS

       GL_INVALID_ENUM is generated if target or pname is not an accepted value.
