/*
|

|
|
This header defines portable wrappers around xlocale foo_l() functions or
|
||
|
|
their MSVC proprietary _foo_l() equivalents when they are available and
|
||
|
|
implements these functions for the "C" locale [only] if they are not. This
|
||
|
|
allows the program running under the default user locale to still use "C"
|
||
|
|
locale for operations such as reading data from files where they are stored
|
||
|
|
using decimal point &c.
|
||
|
|
|
||
|
|
TODO: Currently only the character classification and transformation
|
||
|
|
functions and number <-> string functions, are implemented,
|
||
|
|
we also need at least
|
||
|
|
- formatted IO: scanf_l(), printf_l() &c
|
||
|
|
- time: strftime_l(), strptime_l()
