nl_langinfo - get locale values

Syntax	#include <langinfo.h> char *nl_langinfo(nl_item item);
Description	nl_langinfo() returns the value of the constant item in the current locale or environment. The available constants and values for item are defined in langinfo.h.
Return val.	Pointer to a string of the locale
		if no langinfo data is defined in an environment.
	Null pointer	if item is invalid.
Notes	The array pointed to by the return value should not be modified by the program, but may be modified by further calls to nl_langinfo(). In addition, calls to setlocale() with a category corresponding to the category of item or to the category LC_ALL may overwrite the array. If setlocale() is not called in an application, the current locale in the POSIX subsystem defaults to "POSIX". The return values of nl_langinfo() are based on the current locale. If the current locale does not contain any value for a given parameter, the corresponding value of the default is returned.
