`create` overloads

== Synopses

Declared in `<bslmt_threadutilimpl_pthread.h>`

Create a new thread of program control having platform specific default attributes (i.e., "stack size", "scheduling priority"), that invokes the specified `function` with a single argument specified by `userData`, and load into the specified `threadHandle`, an identifier that may be used to refer to the thread in future calls to this utility. Return 0 on success, and a non‐zero value otherwise. The behavior is undefined if the `threadHandle` is 0. Note that unless explicitly "detached" (`detach`), a call to `join` must be made once the thread terminates to reclaim any system resources associated with the newly created identifier.

Create a new thread of program control having the specified `attributes` that invokes the specified `function` with a single argument specified by `userData`, and load into the specified `threadHandle` an identifier that may be used to refer to the thread in future calls to this utility. Return 0 on success, and a non‐zero value otherwise. The behavior is undefined if the specified `thread` is 0 or if `attributes.stackSize()` has been set to a negative value other than the unset value. Note that unless explicitly "detached" (by `detach`), or unless the `BSLMT_CREATE_DETACHED` attribute is specified, a call to `join` must be made once the thread terminates to reclaim any system resources associated with the newly created identifier.
