Arguments outside the domain cause undefined results. .PP .I Toascii yields its argument with all bits turned off that are not part of a standard .SM ASCII character; it is intended for compatibility with other systems. .SH CAVEATS .I Toupper and .I tolower are equivalent to the System V macros .I _toupper and .IR _tolower . They are .I not the same as the System V functions .I toupper and .IR tolower . .SH "SEE ALSO" ctype(3), getc(3S).
