ECVT_R(3) Linux Programmer's Manual ECVT_R(3)
NAME
ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a string
SYNOPSIS
#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);
DESCRIPTION
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).
NOTES
These functions are obsolete. Instead, sprintf() is recommended.
CONFORMING TO
These functions are GNU extensions.
