toupper(3c)
toupper(3C) Standard C Library Functions toupper(3C)
NAME
toupper, toupper_l - transliterate lowercase characters to uppercase
SYNOPSIS
#include <ctype.h>
int toupper(int c);
int toupper_l(int c, locale_t locale);
DESCRIPTION
The toupper() and toupper_l() functions have as a domain a type int,
the value of which is representable as an unsigned char or the value of
EOF. If the argument has any other value, the argument is returned un‐
changed. The toupper() function operates in the current locale as set
by setlocale(3C), while toupper_l() uses the locale represented by the
locale argument.
If the argument of toupper() or toupper_l() represents a lowercase let‐
ter, and there exists a corresponding uppercase letter as defined by
character type information in the locale category LC_CTYPE, the result
is the corresponding uppercase letter. All other arguments in the do‐
main are returned unchanged.
The behavior is undefined if the locale argument to toupper_l() is the
special locale object LC_GLOBAL_LOCALE or is not a valid locale object
handle.
RETURN VALUES
On successful completion, toupper() and toupper_l() return the upper‐
case letter corresponding to the argument passed. Otherwise, they re‐
turn the argument unchanged.
ERRORS
No errors are defined.
