Declaration:
char *setlocale(int category,
const char *locale);
Sets or reads location dependent information.
category can be one of the following:
LC_ALL |
Set everything. |
LC_COLLATE |
Affects strcoll and strxfrm functions. |
LC_CTYPE |
Affects all character functions. |
LC_MONETARY |
Affects the monetary information provided by
localeconv function. |
LC_NUMERIC |
Affects decimal-point formatting and the
information provided by localeconv
function. |
LC_TIME |
Affects the strftime function. |
A value of "C" for locale sets the locale to the normal C
translation environment settings (default). A null value
("") sets the native environment settings. A null pointer
(NULL) causes setlocale to return a pointer to the string
associated with this category for the current settings (no
changes occur). All other values are
implementation-specific.
After a successful set, setlocale
returns a pointer to a string which represents the previous
location setting. On failure it returns NULL.
Example:
#include<locale.h>
#include<stdio.h>
int main(void)
{
char *old_locale;
old_locale=setlocale(LC_ALL,"C");
printf("The preivous setting was %s.\n",old_locale);
return 0;
}
