41 .Nd white-space character test
49 .Fn isspace_l "int c" "locale_t locale"
55 functions test for white-space characters.
56 For any locale, this includes the following standard characters:
57 .Bl -column \&`\et''___ \&``\et''___ \&``\et''___ \&``\et''___ \&``\et''___ \&``\et''___
58 .It "\&``\et''" Ta "``\en''" Ta "``\ev''" Ta "``\ef''" Ta "``\er''" Ta "`` ''"
65 return non-zero for these characters only.
66 The value of the argument must be representable as an
73 function takes an explicit
77 function uses the current global or per-thread locale.
83 functions return zero if the character tests false and
84 return non-zero if the character tests true.
88 extension of accepting arguments outside of the range of the
90 type in locales with large character sets is considered obsolete
91 and may not be supported in future releases.
96 functions should be used instead.
