isspace -- white-space character test
Standard C Library (libc, -lc)
The isspace() function tests for the white-space characters. For any
locale, this includes the following standard characters:
``\t'' ``\n'' ``\v'' ``\f'' ``\r'' `` ''
In the "C" locale isspace() successful test is limited to this characters
only. For single C chars locales (see multibyte(3)) the value of the
argument is representable as an unsigned char or the value of EOF.
The isspace() function returns zero if the character tests false and
returns non-zero if the character tests true.
Although isspace() accepts arguments outside of the range of the unsigned
char type in locales with large character sets, this is a 4.4BSD extension
and the iswspace() function should be used instead for maximum
ctype(3), iswspace(3), multibyte(3), ascii(7)
The isspace() function conforms to ISO/IEC 9899:1990 (``ISO C89'').
