Functions | |
| int | initFilesMmap (void) |
| open required files, mmap theurt data structures uses global variables for files and mmap-ed data so they are accessible everywhere | |
| int | initParams (int daemon_bit) |
| give a chance for other applications to initialize P_* parameters related to autoexposure functionality so the daemon itself can be started early | |
Variables | |
| int | fd_fparmsall |
| Global variables. | |
