-.Pp
-The individual fields have the following meanings:
-.Pp
-.Bl -tag -width mon_decimal_point
-.It Fa decimal_point
-The decimal point character, except for currency values,
-can't be the empty string.
-.It Fa thousands_sep
-The separator between groups of digits
-before the decimal point, except for currency values.
-.It Fa grouping
-The sizes of the groups of digits, except for currency values.
-This is a pointer to a vector of integers, each of size
-.Va char ,
-representing group size from low order digit groups
-to high order (right to left).
-The list may be terminated with 0 or
-.Dv 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
-.Dv CHAR_MAX ,
-no more grouping is performed.
-.It Fa int_curr_symbol
-The standardized international currency symbol.
-.It Fa currency_symbol
-The local currency symbol.
-.It Fa mon_decimal_point
-The decimal point character for currency values.
-.It Fa mon_thousands_sep
-The separator for digit groups in currency values.
-.It Fa mon_grouping
-Like
-.Fa grouping
-but for currency values.
-.It Fa positive_sign
-The character used to denote nonnegative currency values,
-usually the empty string.
-.It Fa negative_sign
-The character used to denote negative currency values,
-usually a minus sign.
-.It Fa int_frac_digits
-The number of digits after the decimal point
-in an international-style currency value.
-.It Fa frac_digits
-The number of digits after the decimal point
-in the local style for currency values.
-.It Fa p_cs_precedes
-1 if the currency symbol precedes the currency value
-for nonnegative values, 0 if it follows.
-.It Fa p_sep_by_space
-1 if a space is inserted between the currency symbol
-and the currency value for nonnegative values, 0 otherwise.
-.It Fa n_cs_precedes
-Like
-.Fa p_cs_precedes
-but for negative values.
-.It Fa n_sep_by_space
-Like
-.Fa p_sep_by_space
-but for negative values.
-.It Fa p_sign_posn
-The location of the
-.Fa positive_sign
-with respect to a nonnegative quantity and the
-.Fa currency_symbol ,
-coded as follows:
-.Bl -tag -width 3n -compact
-.It Li 0
-Parentheses around the entire string.
-.It Li 1
-Before the string.
-.It Li 2
-After the string.
-.It Li 3
-Just before
-.Fa currency_symbol .
-.It Li 4
-Just after
-.Fa currency_symbol .
-.El
-.It Fa n_sign_posn
-Like
-.Fa p_sign_posn
-but for negative currency values.
-.It Fa int_p_cs_precedes
-Same as
-.Fa p_cs_precedes ,
-but for internationally formatted monetary quantities.
-.It Fa int_n_cs_precedes
-Same as
-.Fa n_cs_precedes ,
-but for internationally formatted monetary quantities.
-.It Fa int_p_sep_by_space
-Same as
-.Fa p_sep_by_space ,
-but for internationally formatted monetary quantities.
-.It Fa int_n_sep_by_space
-Same as
-.Fa n_sep_by_space ,
-but for internationally formatted monetary quantities.
-.It Fa int_p_sign_posn
-Same as
-.Fa p_sign_posn ,
-but for internationally formatted monetary quantities.
-.It Fa int_n_sign_posn
-Same as
-.Fa n_sign_posn ,
-but for internationally formatted monetary quantities.
-.El
-.Pp
-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
-.Dv CHAR_MAX
-result similarly denotes an unavailable value.
