ISSPACE(3) BSD Library Functions Manual ISSPACE(3)
NAME
isspace -- white-space character test
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isspace(int c);
DESCRIPTION
The isspace() function tests for the white-space characters. For any locale, this includes the follow-ing following
ing standard characters:
``\t'' ``\n'' ``\v'' ``\f'' ``\r'' `` ''
In the "C" locale, isspace() successful test is limited to these characters only. The value of the
argument must be representable as an unsigned char or the value of EOF.
RETURN VALUES
The isspace() function returns zero if the character tests false and returns non-zero if the character
tests true.
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
iswspace() function should be used instead.
SEE ALSO
ctype(3), isalnum_l(3), iswspace(3), multibyte(3), ascii(7)
STANDARDS
The isspace() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
