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).
RETURN VALUE
These functions return 0 on success, and −1
otherwise.
NOTES
These functions are obsolete. Instead, sprintf(3) is
recommended.
CONFORMING TO
These functions are GNU extensions.
