Need help with "#define" syntax ending with semicolon

[slrj]

Can someone explain me what's going on in the code below. As per my knowledge "#define <macro name> <Macro replacement>" doesn't have a semicolon and it's terminated by a new line. But the code line in bold below has a semicolon and is followed by a function declaration. (This is a piece of working, complied code)

  #define CST_CC_ERR LogMsg; s_ReportCSTFailure // Sets __FILE__ and __LINE__
 
  static void s_ReportCSTFailure( const string& msg, int rc, CST_LOG_ID logID,  ccAuthViewR* out )
 {
....
 
}

You knowledge is correct and this does fit

"#define <macro name> <Macro replacement>"

as follows

#define CST_CC_ERR LogMsg; s_ReportCSTFailure // Sets __FILE__ and __LINE__


<macro name> = "CST_CC_ERR"
<Macro replacement> = "LogMsg; s_ReportCSTFailure"

i.e. everything following the macro name up to the new line excluding comments

When used the replace ment is then the statement

LogMsg;

I do not know what that is meant to do followed by the function name

s_ReportCSTFailure

I imagine this macro is meant to be used as

CST_CC_ERR(msg, rc, logID, out);

i.e. the parameters to s_ReportCSTFailure follow the macro, the macro is used instead of calling the function directly so that the extra expression LogMsg; is also executed.

Banfa,

Thanks for your explanation. It make sense now.

Thanks.
