CommandLine(
    xref:BloombergLP/balcl/OptionInfo.adoc[OptionInfo] const(& specTable)[],
    std::ostream& errorStream,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* basicAllocator = 0);
----

== Description

Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `specTable` satisfies the `isValidOptionSpecificationTable` function. Note that an appropriate error message is written to the specified `errorStream`.
