function.

The locale.h header declares the lconv structure defined as follows:

.nf
char *currency_symbol
char *decimal_point
char frac_digits
char *grouping
char *int_curr_symbol
char int_frac_digits
char int_n_cs_precedes
char int_n_sep_by_space
char int_n_sign_posn
char int_p_cs_precedes
char int_p_sep_by_space
char int_p_sign_posn
char *mon_decimal_point
char *mon_grouping
char *mon_thousands_sep
char *negative_sign
char n_cs_precedes
char n_sep_by_space
char n_sign_posn
char *positive_sign
char p_cs_precedes
char p_sep_by_space
char p_sign_posn
char *thousands_sep
.fi
