.func _mbctoupper
#include <mbstring.h>
unsigned int _mbctoupper( unsigned int c );
.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function converts a lowercase multibyte character to an
equivalent uppercase multibyte character.
.np
For example, in code page 932, this includes the single-byte lowercase
letters a-z and the double-byte lowercase characters such that:
.millust begin
0x8281 <= c <= 0x829A
.millust end
.np
.bd Note:
This function was called
.kw jtoupper
in earlier versions.
.desc end
.return begin
The &func function returns the argument value if the argument is not a
double-byte lowercase character;
otherwise, the equivalent uppercase character is returned.
.return end
