NAME
ecvt_r, fcvt_r, qecvt_r, qfcvt_r − convert a floating-point number to a string
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);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
ecvt_r(), fcvt_r(), qecvt_r(), qfcvt_r():
_SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE >= 500
DESCRIPTION
The functions ecvt_r(), fcvt_r(), qecvt_r() and qfcvt_r() are identical 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.
CONFORMING TO
These functions are GNU extensions.
NOTES
These functions are obsolete. Instead, sprintf(3) is recommended.
