[NTLUG:Discuss] C questions

[Fred James]

All
Can anyone confirm for me that
    //
is not an allowed syntax for a commnet line in ANSI C, please?
(example:
    // line of text
should be
    /* line of text */
)

Can anyone confirm for me that
    _EXPORT is not a part of extern in ANSI C, please?
(example:
    extern _EXPORT DataTable*      createDataTable();
should be
    extern DataTable*      createDataTable();
)

Thank you in advance for any help you may be able to offer
Regards
Fred James
