#include <locale.h>struct lconv *localeconv(void);

The localeconv( ) function returns a pointer to a structure of type lconv, which contains various geopolitical environmental information relating to the way numbers are formatted. The lconv structure contains the following members:

char *decimal_point;     /* Decimal point character                             for nonmonetary values. */ char *thousands_sep;     /* Thousands separator                             for nonmonetary values. */ char *grouping;          /* Specifies grouping for                             nonmonetary values. */ char *int_curr_symbol;   /* International currency symbol. */ char *currency_symbol;   /* Local currency symbol. */ char *mon_decimal_point; /* Decimal point character for                             monetary values. */ char *mon_thousands_sep; /* Thousands separator for                             values. */ char *mon_grouping;      /* Specifies grouping for                             monetary values. */ char *positive_sign;     /* Positive value indicator for                             monetary values. */ char *negative_sign;     /* Negative value indicator for                             monetary values. */ char int_frac_digits;    /* Number of digits displayed to the                             right of the decimal point for                             monetary values displayed using                             international format. */ char frac_digits;        /* Number of digits displayed to the                             right of the decimal point for                             monetary values displayed using                             local format. */ char p_cs_precedes;      /* 1 if currency symbol precedes                             positive value, 0 if currency                             symbol follows value. */ char p_sep_by_space;     /* 1 if currency symbol is                             separated from value by a space,                              0 otherwise.

Applies to                              internationally formatted values. */ char _n_sep_by_space;    /* Indicates the separation between the                             currency symbol, sign, and a negative value.                             Applies to internationally formatted values. */ char _p_sign_posn;       /* Indicates position of                             positive value symbol.
