ecvt_r

SYNOPSIS
       #include <stdlib.h>

       int ecvt_r(double number, int ndigits, int *decpt,
                  int *sign, char *buf, size_t len);

       int fcvt_r(double number, int ndigits, int *decpt,
                  int *sign, char *buf, size_t len);

       int qecvt_r(long double number, int ndigits, int *decpt,
                  int *sign, char *buf, size_t len);

       int qfcvt_r(long double number, int ndigits, int *decpt,
                  int *sign, char *buf, size_t len);

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

RETURN VALUE
       These functions return 0 on success, and -1 otherwise.
