# static

The default Storage-Class Specifier for global variables which makes the variable available only to functions within the current file. You can also define a static variable within a function. The variable is initialized at compilation time and retains it value between calls.

## Example

The following example shows a static variable, logon_done, used as a boolean flag to execute the logon procedure once only. logon_done retains its value between each call to Action(). Once it is set to 1, it never again attempts to log on to the server.

        #define MAX_RETRIES 5
        static int logon_done = 0;
        int retry; // Attempt to logon MAX_TRIES

        if (!logon_done) {

     // logon to server here and break out of loop if successful

        for (retry=0; retry<MAX_RETRIES; retry++)
            lr_output_message ("Retry number %d", retry);
            logon_done = 1;
        }

    Example: Output:
    Action.c(12): Retry number 0
    Action.c(12): Retry number 1
    Action.c(12): Retry number 2
    Action.c(12): Retry number 3
    Action.c(12): Retry number 4
