C庫函式struct lconv *localeconv(void)設定或讀取位置相關的資訊。在這些傳回在一個物件中的lconv結構型別。
以下是localeconv()函式的宣告。
struct lconv *localeconv(void)
NA
這個函式返回一個指向一個struct lconv目前的語言環境，具有以下結構：
typedef struct { char *decimal_yiibai; char *thousands_sep; char *grouping; char *int_curr_symbol; char *currency_symbol; char *mon_decimal_yiibai; char *mon_thousands_sep; char *mon_grouping; char *positive_sign; char *negative_sign; char int_frac_digits; char frac_digits; char p_cs_precedes; char p_sep_by_space; char n_cs_precedes; char n_sep_by_space; char p_sign_posn; char n_sign_posn; } lconv
下面的例子演示了如何使用localeconv()函式。
#include <locale.h> #include <stdio.h> int main () { struct lconv * lc; setlocale(LC_MONETARY, "it_IT"); lc = localeconv(); printf("Local Currency Symbol: %s ",lc->currency_symbol); printf("International Currency Symbol: %s ",lc->int_curr_symbol); setlocale(LC_MONETARY, "en_US"); lc = localeconv(); printf("Local Currency Symbol: %s ",lc->currency_symbol); printf("International Currency Symbol: %s ",lc->int_curr_symbol); setlocale(LC_MONETARY, "en_GB"); lc = localeconv(); printf ("Local Currency Symbol: %s ",lc->currency_symbol); printf ("International Currency Symbol: %s ",lc->int_curr_symbol); printf("Decimal Yiibai = %s ", lc->decimal_yiibai); return 0; }
讓我們編譯和執行上面的程式，這將產生以下結果：
Local Currency Symbol: EUR International Currency Symbol: EUR Local Currency Symbol: $ International Currency Symbol: USD Local Currency Symbol: £ International Currency Symbol: GBP Decimal Yiibai = .
