fmt_strn - write an ASCII string
#include <fmt.h>
size_t fmt_strn(char *dest,const char
*source,
size_t maxlen);
fmt_str copies at most maxlen leading nonzero bytes from source to dest and returns the number of bytes it copied.
fmt_str does not append \0.
If dest equals FMT_LEN (i.e. is zero), fmt_strn returns the number of bytes it would have written.
