.Lb libc

SYNOPSIS


.In ctype.h int tolower "int c"

DESCRIPTION

The tolower function converts an upper-case letter to the corresponding lower-case letter. For single C char s locales (see multibyte(3)) the value of the argument is representable as an unsigned char or the value of EOF.

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 BSD 4.4 extension of accepting arguments outside of the range of the
.Vt "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.
