Internal environment\&. Values can be set one of two ways: 1\&. In config file 'var = value'\&. The default config file path is libstdcxx-profile\&.conf\&. 2\&. By setting process environment variables\&. For instance, in a Bash shell you can set the unit cost of iterating through a map like this: export __map_iterate_cost_factor=5\&.0\&. If a value is set both in the input file and through an environment variable, the environment value takes precedence\&.

.PP
Final report method, registered with \fBatexit\fP\&. This can also be called directly by user code, including signal handlers\&. It is protected against deadlocks by the reentrance guard in profiler\&.h\&. However, when called from a signal handler that triggers while within __gnu_profile (under the guarded zone), no output will be produced\&.
