tolower(3C) Standard C Library Functions tolower(3C)NAME
tolower - transliterate upper-case characters to lower-case
SYNOPSIS
#include <ctype.h>
int tolower(int c);
DESCRIPTION
The tolower() function has 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 unchanged. If the argument of tolower() represents an upper-case letter, and there
exists a corresponding lower-case letter (as defined by character type information in the program locale category LC_CTYPE), the result
is the corresponding lower-case letter. All other arguments in the domain are returned unchanged.
RETURN VALUES
On successful completion, tolower() returns the lower-case letter corresponding to the argument passed. Otherwise, it returns the argument
unchanged.
ERRORS
No errors are defined.
