/** Thread local storage.
|
|
|
|
A minimal wrapper that should be implementable across many compilers,
|
|
and implementable efficiently across most modern compilers.
|
|
|
|
Thread locals have type intptr_t.
|
|
|
|
Declaring a thread local variable 'foo':
|
|
GPR_TLS_DECL(foo);
|
|
Thread locals always have static scope.
|
|
|
|
Initializing a thread local (must be done at library initialization
|
|
time):
|
|
gpr_tls_init(&foo);
|
|
|
|
Destroying a thread local:
|
|
gpr_tls_destroy(&foo);
|
|
|
|
Setting a thread local (returns new_value):
|
|
gpr_tls_set(&foo, new_value);
|
|
|
|
Accessing a thread local:
|
|
current_value = gpr_tls_get(&foo);
|
|
|
|
ALL functions here may be implemented as macros. */
