SYNOPSIS

11
12       int ecvt_r(double number, int ndigits, int *decpt,
13                  int *sign, char *buf, size_t len);
14
15       int fcvt_r(double number, int ndigits, int *decpt,
16                  int *sign, char *buf, size_t len);
17
18       int qecvt_r(long double number, int ndigits, int *decpt,
19                  int *sign, char *buf, size_t len);
20
21       int qfcvt_r(long double number, int ndigits, int *decpt,

DESCRIPTION

30       The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical
31       to ecvt(3), fcvt(3), qecvt(3) and qfcvt(3), respectively,  except  that
32       they do not return their result in a static buffer, but instead use the
33       supplied buf of size len.  See ecvt(3) and qecvt(3).
34

RETURN VALUE

36       These functions return 0 on success, and -1 otherwise.
37

CONFORMING TO

39       These functions are GNU extensions.
40

NOTES

42       These functions are obsolete.  Instead, sprintf(3) is recommended.
