2.6.3 localeconv
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 isCHAR_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. |
