79.Pp 80The 81.Fn isalnum_l 82function takes an explicit locale argument, whereas the 83.Fn isalnum 84function uses the current global or per-thread locale. |
85.Sh RETURN VALUES 86The 87.Fn isalnum 88function returns zero if the character tests false and 89returns non-zero if the character tests true. 90.Sh COMPATIBILITY 91The 92.Bx 4.4 --- 4 unchanged lines hidden (view full) --- 97The 98.Fn iswalnum 99function should be used instead. 100.Sh SEE ALSO 101.Xr ctype 3 , 102.Xr isalpha 3 , 103.Xr isdigit 3 , 104.Xr iswalnum 3 , |
