This routine returns nonzero if c is a particular representation of a space character.

int isspace(    int c);int iswspace(    wint_t c);

Parameters

  • c
    Integer to test.

Return Values

isspace returns a non-zero value if c is a white-space character (0x09 – 0x0D or 0x20).

iswspace returns a non-zero value if c is a wide character that corresponds to a standard white-space character or is one of an implementation-defined set of wide characters for which iswalnum is false.

Each routine returns 0 if c does not satisfy the test condition.

The result of the test condition for the isspace function depends on the LC_CTYPE category setting of the current locale.

For iswspace, the result of the test condition is independent of locale.
