#include <stdlib.h>

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

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

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

char *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 are obsolete. Instead, sprintf() is recommended.

These functions are GNU extensions.
