Declaration:
struct lconv *localeconv(void);
Sets the structure lconv to represent the
current location settings.
The string pointers in the structure may point to a null
string ("") which indicates that the value is not available. The
char types are nonnegative numbers. If the value is
CHAR_MAX, then the value is not available.
lconv variables:
char *decimal_point |
Decimal point character used for non-monetary
values.
|
char *thousands_sep |
Thousands place separator character used for
non-monetary values.
|
char *grouping |
A string that indicates the size of each group of
digits in non-monetary quantities. Each character
represents an integer value which designates the number
of digits in the current group. A value of 0 means that
the previous value is to be used for the rest of the
groups.
|
char *int_curr_symbol |
A string of the international currency symbols used.
The first three characters are those specified by ISO
4217:1987 and the fourth is the character which
separates the currency symbol from the monetary
quantity.
|
char *currency_symbol |
The local symbol used for currency.
|
char *mon_decimal_point |
The decimal point character used for monetary
values.
|
char *mon_thousands_sep |
The thousands place grouping character used for
monetary values.
|
char *mon_grouping |
A string whose elements define the size of the
grouping of digits in monetary values. Each character
represents an integer value which designates the number
of digits in the current group. A value of 0 means that
the previous value is to be used for the rest of the
groups.
|
char *positive_sign |
The character used for positive monetary values.
|
char *negative_sign |
The character used for negative monetary values.
|
char int_frac_digits |
Number of digits to show after the decimal point in
international monetary values.
|
char frac_digits |
Number of digits to show after the decimal point in
monetary values.
|
char p_cs_precedes |
If equal to 1, then the currency_symbol
appears before a positive monetary value. If equal to 0,
then the currency_symbol appears
after a positive monetary value.
|
char p_sep_by_space |
If equal to 1, then the currency_symbol
is separated by a space from a positive monetary value.
If equal to 0, then there is no space between the
currency_symbol and a positive monetary
value.
|
char n_cs_precedes |
If equal to 1, then the currency_symbol
precedes a negative monetary value. If equal to 0, then
the currency_symbol succeeds a negative
monetary value. |
char n_sep_by_space |
If equal to 1, then the currency_symbol
is separated by a space from a negative monetary value.
If equal to 0, then there is no space between the
currency_symbol and a negative monetary
value.
|
char p_sign_posn |
Represents the position of the
positive_sign in a positive monetary value.
|
char n_sign_posn |
Represents the position of the
negative_sign in a negative monetary value.
|
The following values are used for
p_sign_posn and n_sign_posn:
0 |
Parentheses encapsulate the value and the
currency_symbol. |
1 |
The sign precedes the value and currency_symbol. |
2 |
The sign succeeds the value and currency_symbol. |
3 |
The sign immediately precedes the value and
currency_symbol. |
4 |
The sign immediately succeeds the value and
currency_symbol. |
