The required name argument consists of everything after the colon.

The /name option is intended to be given as a directive in an object file, and only then when building a VxD. The ordinary occurrence would be in an export file created by LIB, with /name resulting from the translation of a NAME or VXD statement in a module definition file. If a /name option (with an argument) is given on the command line or if there is no /vxd option on the command line, then LINK treats the /name option as unrecognised and issues warning LNK4044.
