TAU_MAPPING_PROFILE_TIMER \- Declares a mapping timer

.SH "DESCRIPTION"
.PP
TAU_MAPPING_PROFILE_TIMER
enables timing of individual statements, instead of complete blocks. It will attribute the time to a higher\-level statement. The second argument is the identifier of the statement that is obtained after
TAU_MAPPING_OBJECT
and
TAU_MAPPING_LINK
have executed. The timer argument in this macro is any variable that is used subsequently to start and stop the timer.
