HELP! TYPEDEF

[ashes jingles]

What do you make of this [1] thing in the code below. I have no clue. Your help will be greatly appreciated.

typedef struct
{
int8 font;
uchar path;
} txtspec;
typedef txtspec tspec[1];
typedef tspec *tspecptr;
typedef tspecptr *tspechandle;




Thanks

> typedef txtspec tspec[1];

This makes tspec[1] a type synonym for txtspec. The syntax '[1]' is that of an array with one element, e.g:

char foo[1]; // declares foo as an array of 1 char

The typedef looks a bit unusual, but it's just another way of referring to the txtspec struct.

To clarify a bit, if you declare a variable of type tspec:

tspec pfoo;

pfoo will be a single-element array of txtspec. The following code would have the same result:

txtspec foo;
txtspec* pfoo = foo;
