NAME

ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a string

LIBRARY

Standard C library ( libc , -lc )

SYNOPSIS

#include <stdlib.h>

[[deprecated]] int ecvt_r(double number , int ndigits ,
int *restrict decpt , int *restrict sign ,
char *restrict buf , size_t len );
[[deprecated]] int fcvt_r(double number , int ndigits ,
int *restrict decpt , int *restrict sign ,
char *restrict buf , size_t len );

[[deprecated]] int qecvt_r(long double number , int ndigits ,
int *restrict decpt , int *restrict sign ,
char *restrict buf , size_t len );
[[deprecated]] int qfcvt_r(long double number , int ndigits ,
int *restrict decpt , int *restrict sign ,
char *restrict buf , size_t len );

Feature Test Macro Requirements for glibc (see feature_test_macros (7)):

ecvt_r (), fcvt_r (), qecvt_r (), qfcvt_r ():
/* glibc >= 2.19: */ _DEFAULT_SOURCE
|| /* glibc <= 2.19: */ _SVID_SOURCE || _BSD_SOURCE

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.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes (7).
