LOCALECONV(3) BSD Library Functions Manual LOCALECONV(3) NAME localeconv, localeconv_l -- natural language formatting for C LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <locale.h> struct lconv * localeconv(void); #include <xlocale.h> struct lconv * localeconv_l(locale_t loc); DESCRIPTION The localeconv() function returns a pointer to a structure which provides parameters for formatting numbers, especially currency values: struct lconv { 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; char int_p_cs_precedes; char int_n_cs_precedes; char int_p_sep_by_space; char int_n_sep_by_space; char int_p_sign_posn; char int_n_sign_posn; }; The individual fields have the following meanings: decimal_point The decimal point character, except for currency val-ues, values, ues, cannot be an empty string. thousands_sep The separator between groups of digits before the dec-imal decimal imal point, except for currency values. grouping The sizes of the groups of digits, except for currency values. This is a pointer to a vector of integers, each of size char, representing group size from low order digit groups to high order (right to left). The list may be terminated with 0 or CHAR_MAX. If the list is terminated with 0, the last group size before the 0 is repeated to account for all the digits. If the list is terminated with CHAR_MAX, no more grouping is performed. 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 val-ues, values, ues, 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 oth-erwise. otherwise. erwise. 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 format-ted formatted ted monetary quantities. int_n_cs_precedes Same as n_cs_precedes, but for internationally format-ted formatted ted monetary quantities. int_p_sep_by_space Same as p_sep_by_space, but for internationally for-matted formatted matted monetary quantities. int_n_sep_by_space Same as n_sep_by_space, but for internationally for-matted formatted matted 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. While the localeconv() function uses the current locale, the localeconv_l() function may be passed a locale directly. See xlocale(3) for more information. RETURN VALUES The localeconv() function returns a pointer to a static object which may be altered by later calls to setlocale(3) or localeconv(). ERRORS No errors are defined. SEE ALSO setlocale(3), strfmon(3), xlocale(3) STANDARDS The localeconv() function conforms to ISO/IEC 9899:1999 (``ISO C99''). HISTORY The localeconv() function first appeared in 4.4BSD.
