.desc begin
The &func function fills the string
.arg str
with the value of the argument
.arg fill,
When the value of
.arg len
is greater than the length of the string, the entire string is filled.
Otherwise, that number of characters at the start of the string are set
to the fill character.
.np
&func is similar to
.kw _mbsnset,
except that it fills in
.arg count
bytes rather than
.arg count
characters.
If the number of bytes to be filled is odd and
.arg fill
is a double-byte character, the partial byte at the end is filled with
an ASCII space character.
.im farfunc

The address of the original string
.arg str
is returned.
