[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
#define BSLMT_THREAD_LOCAL_VARIABLE(BASIC_TYPE, VARIABLE_NAME, INITIAL_VALUE)

----

== Description

Define, at function or namespace scope, a thread‐local `static` variable having the specified `VARIABLE_NAME` of the specified `BASIC_TYPE`, initialized with the specified `INITIAL_VALUE`. If `VARIABLE_NAME` is not a valid variable name, or `INITIAL_VALUE` is not convertible to the type `BASIC_TYPE`, the instantiation of this macro will result in a compile time error. The behavior is undefined unless `INITIAL_VALUE` is a _compile_ _time_ constant value.

== Parameters
