fmt_longlong (3)

#include <fmt.h>

size_t fmt_longlong(char *dest,long long source);

fmt_longlong writes an ASCII representation ('-' and '0' to '9', base 10) of source to dest and returns the number of bytes written.

fmt_longlong does not append \0.

If dest equals FMT_LEN (i.e. is zero), fmt_longlong returns the number of bytes it would have written.

For convenience, fmt.h defines the integer FMT_LONG to be big enough to contain every possible fmt_longlong output plus \0.
