localeconv() - C函數

C庫函數struct lconv *localeconv(void)設置或讀取位置相關的信息。在這些傳回在一個對象中的lconv結構類型。

聲明

以下是localeconv()函數的聲明。

struct lconv *localeconv(void)

參數

• NA

返回值

這個函數返回一個指向一個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

例子

下面的例子演示瞭如何使用localeconv()函數。

#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; }

讓我們編譯和運行上面的程序，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 = .
