decimal_point The decimal point character, except for currency values, cannot be an empty string. thousands_sep The separator between groups of digits before the decimal point, except for currency values. grouping The sizes of the groups of digits, except for currency values. int_curr_symbol The standardized international currency symbol. currency_symbol The local currency symbol. mon_decimal_point The decimal point character for currency values. mon_thousands_sep The separator for digit groups in currency values. mon_grouping Like grouping but for currency values. positive_sign The character used to denote nonnegative currency values, usually the empty string. negative_sign The character used to denote negative currency values, usually a minus sign. int_frac_digits The number of digits after the decimal point in an international-style currency value. frac_digits The number of digits after the decimal point in the local style for currency values. p_cs_precedes 1 if the currency symbol precedes the currency value for nonnegative values, 0 if it follows. p_sep_by_space 1 if a space is inserted between the currency symbol and the currency value for nonnegative values, 0 otherwise. n_cs_precedes Like p_cs_precedes but for negative values. n_sep_by_space Like p_sep_by_space but for negative values. p_sign_posn The location of the positive_sign with respect to a nonnegative quantity and the currency_symbol, coded as follows:
0 Parentheses around the entire string. 1 Before the string. 2 After the string. 3 Just before currency_symbol. 4 Just after currency_symbol.
n_sign_posn Like p_sign_posn but for negative currency values. int_p_cs_precedes Same as p_cs_precedes, but for internationally formatted monetary quantities. int_n_cs_precedes Same as n_cs_precedes, but for internationally formatted monetary quantities. int_p_sep_by_space Same as p_sep_by_space, but for internationally formatted monetary quantities. int_n_sep_by_space Same as n_sep_by_space, but for internationally formatted monetary quantities. int_p_sign_posn Same as p_sign_posn, but for internationally formatted monetary quantities. int_n_sign_posn Same as n_sign_posn, but for internationally formatted monetary quantities.
Unless mentioned above, an empty string as a value for a field indicates a zero length result or a value that is not in the current locale. A CHAR_MAX result similarly denotes an unavailable value.
Note: By default smartphone's monetary settings will be returned from the localeconv instead of "C" structure

The setlocale function sets the C librarys notion of natural language formatting style for particular sets of routines. Each such style is called a 'locale' and is invoked using an appropriate name passed as a C string. The setlocale function recognizes several categories of routines. These are the categories and the sets of routines they select:
LC_ALL Set the entire locale generically. LC_COLLATE Set a locale for string collation routines. Currently locale setting does not have effect on this category. LC_CTYPE This controls recognition of upper and lower case, alphabetic or non-alphabetic characters, and so on. Currently locale setting does not have effect on this category. LC_MESSAGES Set a locale for message catalogs. Currently this category is not supported. LC_MONETARY Set a locale for formatting monetary values; this affects the localeconv function. LC_NUMERIC Set a locale for formatting numbers. This controls the formatting of decimal points in input and output of floating point numbers in functions such as printf and scanf, as well as values returned by localeconv. LC_TIME Set a locale for formatting dates and times using the strftime function.
Only three locales are defined by default, the empty string which denotes the native environment, and the C and POSIX locales, which denote the C language environment. A locale argument of NULL causes setlocale to return the current locale. By default, C programs start in the C locale. The only function in the library that sets the locale is setlocale; the locale is never changed as a side effect of some other routine.
