/*

|
*ctype - Function versions of ctype macros
|
|
|
|
*Purpose:
|
|
* Function versions of the macros in ctype.h. In order to define
|
|
* these, we use a trick -- we undefine the macro so we can use the
|
|
* name in the function declaration, then re-include the file so
|
|
* we can use the macro in the definition part.
|
|
|
|
* Functions defined:
|
|
* isalpha isupper islower
|
|
* isdigit isxdigit isspace
|
|
* ispunct isalnum isprint
|
|
* isgraph isctrl __isascii
|
|
* __toascii __iscsym __iscsymf
|
|
|
|
*Entry:
|
|
* int c = character to be tested
|
|
*Exit:
|
|
* returns non-zero = character is of the requested type
|
|
* 0 = character is NOT of the requested type
|
|
|
|
*Exceptions:
|
|
* None.
