2005 Sams Publishing glGetQueryiv 3G 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. glGetQueryObject, glIsQuery Copyright 2005 Addison-Wesley.
