.TH fmt_ulonglong 3
.SH NAME
fmt_ulonglong \- write an ASCII representation of an unsigned long long integer
.SH SYNTAX
.B #include <libowfat/fmt.h>
size_t \fBfmt_ulonglong\fP(char *\fIdest\fR,unsigned long long \fIsource\fR);
.SH DESCRIPTION
fmt_ulonglong writes an ASCII representation ('0' to '9', base 10) of
\fIsource\fR to \fIdest\fR and returns the number of bytes written.
fmt_ulonglong does not append \\0.
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ulonglong returns the
number of bytes it would have written.
For convenience, fmt.h defines the integer FMT_ULONG to be big enough to
contain every possible fmt_ulonglong output plus \\0.
