ecvt_r, fcvt_r, qecvt_r, qfcvt_r − convert a floating-point number to a string
#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);
The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical to ecvt, fcvt, qecvt and qfcvt, 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).
These functions return 0 on success, and −1 otherwise.
These functions are obsolete. Instead, sprintf() is recommended.
These functions are GNU extensions.
