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. SEE ALSO
ecvt(3), qecvt(3), sprintf(3) COLOPHON
