C 库函数 - localeconv()
描述
C 库函数 struct lconv *localeconv(void) 设置或读取地域化信息。它会返回一个 lconv 结构类型的对象。
声明
下面是 localeconv() 函数的声明。
struct lconv *localeconv(void)
参数
- NA
返回值
该函数返回一个指向当前区域 struct lconv 的指针,它的结构如下:
typedef struct { char *decimal_point; char *thousands_sep; char *grouping; char *int_curr_symbol; char *currency_symbol; char *mon_decimal_point; 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
实例
下面的实例演示了 localeconv() 函数的用法。
#include <locale.h> #include <stdio.h> int main () { struct lconv * lc; setlocale(LC_MONETARY, "it_IT"); lc = localeconv(); printf("Local Currency Symbol: %s\n",lc->currency_symbol); printf("International Currency Symbol: %s\n",lc->int_curr_symbol); setlocale(LC_MONETARY, "en_US"); lc = localeconv(); printf("Local Currency Symbol: %s\n",lc->currency_symbol); printf("International Currency Symbol: %s\n",lc->int_curr_symbol); setlocale(LC_MONETARY, "en_GB"); lc = localeconv(); printf ("Local Currency Symbol: %s\n",lc->currency_symbol); printf ("International Currency Symbol: %s\n",lc->int_curr_symbol); printf("Decimal Point = %s\n", lc->decimal_point); return 0; }
让我们编译并运行上面的程序,这将产生以下结果:
Local Currency Symbol: EUR International Currency Symbol: EUR Local Currency Symbol: $ International Currency Symbol: USD Local Currency Symbol: £ International Currency Symbol: GBP Decimal Point = .
