set_exit_status()

void set_exit_status

(

enum exit_status_type

new_status

)

Sets the exit status after a warning or error has occurred. If new_status is E_WARNING and the old exit status was already E_ERROR, the exit status is not changed.

Definition at line 31 of file main.c.

{
    assert(new_status == E_WARNING || new_status == E_ERROR);
 
#if defined(_WIN32) && !defined(__CYGWIN__)
    EnterCriticalSection(&exit_status_cs);
#endif
 
    if (exit_status != E_ERROR)
        exit_status = new_status;
 
#if defined(_WIN32) && !defined(__CYGWIN__)
    LeaveCriticalSection(&exit_status_cs);
#endif
 
    return;
