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.
