# setlocale Function

Selects the appropriate portion of the program’s locale.

Attention: This function is not implemented when building with MPLAB XC8 for PIC MCUs. It is implemented for all other devices and compilers; however, only the default "C" locale is supported.

Include

<locale.h>

Prototype

char * setlocale(int category, const char * locale);

Arguments

 category the portion of the locale to change, specified by macros LC_ALL, LC_NUMERIC etc. locale a string representing the environment to set

Return Value

The function returns a pointer to the string associated with the specified category for the new locale. If the selection cannot be honored, the function returns a null pointer and the program’s locale is not changed. If locale is a null pointer, the function returns a pointer to the string associated with the category for the program’s current locale.

Remarks

The function sets the environment, specified by the locale argument, in the portion of the program’s locale, as specified by the category argument. If locale is a null pointer, the locale is not set.

Those MPLAB XC compilers that implement setlocale() only support the "C" for locale, which specifies the minimal environment for C translation.

Example

See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <locale.h>

struct lconv * ll;

int main(void) {
ll = localeconv();
setlocale(LC_ALL, "C");
}
