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_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

       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.
