Execute a code only one time in C

I want execute a code only one time. I used a solution based on a global varibale of bool type. My question, is it the best solution?

Remark: I use ucos-II.

if (TRUE == Lock)
{
 /*Code to execute one time*/
}

/*The reste of the code*/
Solution

  • A simple code using a static variable.

    static bool once = false;

if (once == false)
{
    once = true;
    // do your "once" stuff here
}
