Locale-independent “atof”?

Question

I'm parsing GPS status entries in fixed NMEA sentences, where fraction part of geographical minutes comes always after period. However, on systems where locale defines comma as decimal separator, atof function ignores period and whole fraction part.

What is the best method to deal with this issue? Long/latitude string in stored in character array, if it matters.

Example Code:

m_longitude = atof((char *)pField); 

Where

pField[] = "01000.3897";

Comment to solution:

Accepted answer is more elegant, but this answer (and comment) is also worth knowing as a quick fix

Answer 1

Any reason why you can't do a setlocale "C" before the atof and restore the locale afterwards? Maybe I misunderstood the question...
