X-Hacker.org- Microsoft C - <b>_tolower() convert 'c' to lowercase</b> http://www.X-Hacker.org [<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
_tolower()               Convert 'c' to Lowercase

 #include   <ctype.h>

 int        _tolower(c);
 int        c;                           Character to be converted

    The _tolower() macro converts 'c' to lowercase. It should only to be
    used when 'c' is known to be an uppercase letter, as the result is
    undefined otherwise.

    Returns:    The converted character 'c'. There is no error return.

      Notes:    Use tolower() to convert a character that is not
                necessarily an uppercase letter.

  -------------------------------- Example ---------------------------------

    The following statements convert a string to lowercase before
    printing it.

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

         char string[15] = "ALPHABET";
         int x;

         main()
         {
             for (x = 0; x < strlen(string); x++)
                 printf("%c",_tolower(string[x]));
             printf("\n");
         }
