char *qgcvt(long double number, int ndigit, char *buf);

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

qecvt(), qfcvt(), qgcvt(): _SVID_SOURCE

Description

The functions qecvt(), qfcvt(), and qgcvt() are identical to ecvt(3) , fcvt(3) , and gcvt(3) respectively, except that they use a long double argument number. See ecvt(3) and gcvt(3) .

Attributes

Multithreading (see pthreads(7) )

The qecvt() and qfcvt() functions are not thread-safe.

Conforming to
