| I want to check if a string to make sure that it only consists of spaces, letters, and numbers. I did something like this:
for ( let = argument; *let != '\0'; let++ )
{
if ( !isalpha(*let) )
{
send_to_char( "The clan name must only have letters in it.\n\r", ch );
return;
}
}
But a space would mean isalpha returns FALSE. Is there another function to use? |

| Yes. You can add a call to isspace() and it should do the trick.
Like so:
for ( let = argument; *let != '\0'; let++ )
{
if ( !isalpha(*let) && !isspace(*let) )
{
send_to_char( "The clan name must only have letters in it.\n\r", ch );
return;
}
}

| If you want numbers too you'll probably want to use isalnum() instead of isalpha().
