localeconv(), localeconv_l

get locale-specific symbols 

Function

SYNOPSIS

#include <locale.h>

struct lconv *localeconv(void);

struct lconv *localeconv_l(locale_t locale);

DESCRIPTION

The localeconv() function returns a pointer to an lconv struct that has values for locale-specific symbols. Members of the structure lconv are either char or pointers to char. The pointers to char are null-terminated, possibly zero-length strings. Members that are type char have either the value of the symbol, or have the value CHAR_MAX to indicate that the symbol has no definition in the current locale.

localeconv_l() behaves in the same way as localeconv() without the _l suffix, but uses the specified locale rather than the global or per-thread locale. A locale_t is returned by newlocale().

The members of struct lconv are:

char *decimal_point 

The radix character used to format nonmonetary quantities. This string is never empty.

char *thousands_sep 

The character used to separate groups of digits before the radix character in formatted nonmonetary quantities.

char *grouping 

A string whose elements indicate the size of each group of digits in formatted nonmonetary quantities.

char *int_curr_symbol 

The international currency symbol applicable to the current locale.

char *currency_symbol 

The local currency symbol applicable to the current locale.

char *mon_decimal_point 

The radix character used to format monetary quantities.

char *mon_thousands_sep 

The separator for groups of digits before the radix character in formatted monetary quantities.

char *mon_grouping 

A string whose elements indicate the size of each group of digits in formatted monetary quantities.

char *positive_sign 

The character used to indicate that a formatted monetary quantity is nonnegative.

char *negative_sign 

The character used to indicate that a formatted monetary quantity is negative.

char int_frac_digits 

The number of digits to be displayed following the radix character in an internationally formatted monetary quantity.

char frac_digits 

The number of digits to be displayed following the radix character in a locally formatted monetary quantity.

char p_cs_precedes 

Boolean value to indicate whether the currency_symbol precedes the value for a nonnegative formatted monetary quantity.

char p_sep_by_space 

Boolean value to indicate whether the currency_symbol is separated by a space from the value for a nonnegative formatted monetary quantity.

char n_cs_precedes 

Boolean value to indicate whether the currency_symbol precedes the value for a negative formatted monetary quantity.

char n_sep_by_space 

Boolean value to indicate whether the currency_symbol is separated by a space from the value for a negative formatted monetary quantity.

char p_sign_posn 

Set to a value indicating the position of the positive_sign for a nonnegative formatted monetary quantity.

char n_sign_posn 

Set to a value indicating the position of the negative_sign for a negative formatted monetary quantity.

The values of p_sign_posn and n_sign_posn are defined as follows:

0 

Parentheses surround the quantity and currency_symbol.

1 

The sign precedes the quantity and currency_symbol.

2 

The sign follows the quantity and currency_symbol.

3 

The sign immediately precedes the currency_symbol.

4 

The sign immediately follows the currency_symbol.

PARAMETERS

None.

RETURN VALUES

A pointer to static storage that holds a filled-in lconv structure. Subsequent calls to localeconv() or localeconv_l() overwrite this area.

CONFORMANCE

localeconv() conforms to ANSI/ISO 9899:1990 'ISO C90'

localeconv_l() conforms to ANSI/ISO 9899:1999 'ISO C99'

PARAMETERS

locale 

Is a locale_t perhaps returned by newlocale() or LC_GLOBAL_LOCALE or 0 for the current thread locale set with uselocale().

MULTITHREAD SAFETY LEVEL

MT-Safe, with exceptions.

The function localeconv() is MT-Safe as long as no thread calls setlocale() while this function is executing.

The function localeconv_l() is MT-Safe as long as no thread calls freelocale() on locale while this function is executing.

PORTING ISSUES

None.
