+
+ Thread locals have type intptr_t.
+
+ Declaring a thread local variable 'foo':

+ Declaring a thread local class variable 'foo':
+ GPR_TLS_CLASS_DECL(foo);

+ Defining the thread local class variable:

+
+ Initializing a thread local (must be done at library initialization
+ time):
+ gpr_tls_init(&foo);
+
+ Destroying a thread local:
