# towupper

From cppreference.com
< c‎ | string‎ | wide

Defined in header `<wctype.h>` |  |
wint_t towupper( wint_t ch ); |  |

Converts the given wide character to uppercase, if possible.

### [edit] Parameters

ch | - | wide character to be converted

### [edit] Return value

Uppercase version of `ch` or unmodified `ch` if no uppercase version is listed in the current C locale.

### [edit] Notes

Only 1:1 character mapping can be performed by this function, e.g. the uppercase form of 'ß' is (with some exceptions) the two-character string "SS", which cannot be obtained by towupper.
