structure errors - C

[samdomville]

Hello - I have a structure which looks good to me:

typedef struct t_settings
{
  :
  BOOL var1;

  Obj1 var2;
  :
} settings;

firstly, what is the "t_" before the structure name mean?

also, I get an error saying syntax error before Obj1...and then a warning saying that no semicolon after struct or union. Why?

Thanks!

BOOL should be typedefed some where...
What is the use of : in the structure.....

I put : there just to show that there is code above and after what I typed, but the compiler did not complain about them...please advise. thanks!

I see no type definition of Obj1 in the posted code, are you sure you have included the file where it is defined?

The "t_" is nothing special, it is not uncommon to insert "t_" or "tag" before (or after) the structure name when typedefing a structure to differentiate it from the type name. On my current project we use a "s" prescript on the structure name and a "T" prescript on the typedef name.
