A copy of the license is included in the ``GNU Free @c Documentation License'' file as part of this distribution. The @code{c-strtod} module contains a string to number (@samp{double}) conversion function operating on single-byte character strings, that operates as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: @smallexample extern double c_strtod (const char *string, char **endp); @end smallexample In particular, only a period @samp{.} is accepted as decimal point, even when the current locale's notion of decimal point is a comma @samp{,}, and no characters outside the basic character set are accepted. On platforms without @code{strtod_l}, this function is not safe for use in multi-threaded applications since it calls @code{setlocale}.
