TOUPPER(3) BSD Library Functions Manual TOUPPER(3)NAME
toupper -- lower case to upper case letter conversion
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
toupper(int c);
DESCRIPTION
The toupper() function converts a lower-case letter to the corresponding upper-case letter. The argument must be representable as an
unsigned char or the value of EOF.
RETURN VALUES
If the argument is a lower-case letter, the toupper() function returns the corresponding upper-case letter if there is one; otherwise, the
argument is returned unchanged.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The towupper() function should be used instead.
SEE ALSO ctype(3), isupper(3), towupper(3)STANDARDS
The toupper() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

tolower, tolower_l -- upper case to lower case letter conversion
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
tolower(int c);
#include <ctype.h>
#include <xlocale.h>
int
tolower_l(int c, locale_t loc);
DESCRIPTION
The tolower() function converts an upper-case letter to the corresponding lower-case letter. The argument must be representable as an
unsigned char or the value of EOF.
Although the tolower() function uses the current locale, the tolower_l() function may be passed a locale directly. See xlocale(3) for more
information.
RETURN VALUES
If the argument is an upper-case letter, the tolower() function returns the corresponding lower-case letter if there is one; otherwise, the
argument is returned unchanged.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The towlower() function should be used instead.
