+.Sh DESCRIPTION
+The
+.Fn strtoi
+function
+converts the string in
+.Fa nptr
+to an
+.Ft intmax_t
+value.
+The
+.Fn strtoi
+function uses internally
+.Xr strtoimax 3
+and ensures that the result is always in the range [
+.Fa lo ..
+.Fa hi
+].
+In adddition it always places
+.Dv 0
+on success or a conversion status in the
+.Fa rstatus
+argument, avoiding the
+.Dv errno
+gymnastics the other functions require.
+The
+.Fa rstatus
+argument can be
+.Dv NULL
+if conversion status is to be ignored.
+.Pp
+The string may begin with an arbitrary amount of white space
+(as determined by
+.Xr isspace 3 )
+followed by a single optional
+.Ql +
+or
+.Ql -
+sign.
+If
+.Fa base
+is zero or 16,
+the string may then include a
+.Ql 0x
+or
+.Ql 0X
+prefix,
+and the number will be read in base 16; otherwise,
+.\" if the
+.\" .Fa base
+.\" is zero or 2,
+.\" the string may then include a
+.\" .Ql 0b
+.\" or
+.\" .Ql 0B
+.\" prefix,
+.\" and the number will be read in base 2; otherwise,
+a zero
+.Fa base
+is taken as 10 (decimal) unless the next character is
+.Ql 0 ,
+in which case it is taken as 8 (octal).
+.Pp
+The remainder of the string is converted to a
+.Em intmax_t
+value in the obvious manner,
+stopping at the first character which is not a valid digit
+in the given base.
+(In bases above 10, the letter
+.Ql A
+in either upper or lower case
+represents 10,
+.Ql B
+represents 11, and so forth, with
+.Ql Z
+representing 35.)
+.Pp
+If
+.Fa endptr
+is non-nil,
+.Fn strtoi
+stores the address of the first invalid character in
+.Fa *endptr .
+If there were no digits at all, however,
+.Fn strtoi
+stores the original value of
+.Fa nptr
+in
+.Fa *endptr .
+(Thus, if
+.Fa *nptr
+is not
+.Ql \e0
+but
+.Fa **endptr
+is
+.Ql \e0
+on return, the entire string was valid.)
+.Sh RETURN VALUES
+The
+.Fn strtoi
+function
+always returns the closest value in the range specified by
+the
+.Fa lo
+and
+.Fa hi
+arguments.
+.Pp
+The
+.Va errno
+value is guaranteed to be left unchanged.
+.Pp
+Errors are stored as the conversion status in the
+.Fa rstatus
+argument.
+.Sh EXAMPLES
+The following example will always return a number in
+.Dv [1..99]
+range no matter what the input is, and warn if the conversion failed.
+.Bd -literal -offset indent
+int e;
+intmax_t lval = strtoi(buf, NULL, 0, 1, 99, &e);

+.It Bq Er ENOTSUP
