towupper(3C) Standard C Library Functions towupper(3C) NAME
towupper - transliterate lower-case wide-character code to upper-case SYNOPSIS
#include <wchar.h> wint_t towupper(wint_t wc); DESCRIPTION
The towupper() function has as a domain a type wint_t, the value of which must be a character representable as a wchar_t, and must be a wide-character code corresponding to a valid character in the current locale or the value of WEOF. If the argument has any other value, the argument is returned unchanged. If the argument of towupper() represents a lower-case wide-character code (as defined by character type information in the program locale category LC_CTYPE), the result is the corresponding upper-case wide-character code. All other arguments in the domain are returned unchanged. RETURN VALUES
Upon successful completion, towupper() returns the upper-case letter corresponding to the argument passed. Otherwise, it returns the argu- ment unchanged. ERRORS
No errors are defined. ATTRIBUTES

towupper - transliterate lowercase wide-character code to uppercase SYNOPSIS
#include <wctype.h> wint_t towupper(wint_t wc); DESCRIPTION
The towupper() function has as a domain a type wint_t, the value of which the application shall ensure is a character representable as a wchar_t, and a wide-character code corresponding to a valid character in the current locale or the value of WEOF. If the argument has any other value, the behavior is undefined. If the argument of towupper() represents a lowercase wide-character code, and there exists a corre- sponding uppercase wide-character code (as defined by character type information in the program locale category LC_CTYPE ), the result shall be the corresponding uppercase wide-character code. All other arguments in the domain are returned unchanged. RETURN VALUE
Upon successful completion, towupper() shall return the uppercase letter corresponding to the argument passed. Otherwise, it shall return the argument unchanged. ERRORS
