toascii

Usage

   #include <ctype.h>
   int toascii(int c);

Description

   toascii converts c to a character by taking any integer value and
   discarding all but the low order seven bits making up an ascii character.
   If c is already a valid character, then it is returned unchanged.

   Implemented as a macro in ctype.h, toascii is also included as a function
   within the library. Undefining the macros, or not including ctype.h, will
   cause the library functions to be used.

Example 

   #include <ctype.h>
   #include <stdio.h>
   #include <stdlib.h>

   int main()
   {
       printf("Make ascii character [%c]\n",toascii(0x0e));
       return EXIT_SUCCESS;
   }


Return Value

   Returns the low 7 bits of c.
