2.6.2 setlocale
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; }
