The individual fields have the following meanings:

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. 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 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.

The localeconv_l() function takes an explicit locale parameter. For more information, see xlocale(3).
