Collaboration diagram for GPIO line operations:
Modules | |
| Operating on multiple lines | |
| Convenience data structures and helper functions for storing and operating on multiple lines at once. | |
| Line info | |
| Definitions and functions for retrieving kernel information about both requested and free lines. | |
| Line requests | |
| Interface for requesting GPIO lines from userspace for both values and events. | |
| Reading & setting line values | |
| Functions allowing to read and set GPIO line values for single lines and in bulk. | |
| Setting line configuration | |
| Functions allowing modification of config options of GPIO lines requested from user-space. | |
| Line events handling | |
| Structures and functions allowing to poll lines for events and read them, both for individual lines as well as in bulk. Also contains functions for retrieving the associated file descriptors and operate on them for easy integration with standard unix interfaces. | |
| Misc line functions | |
| Functions that didn't fit anywhere else. | |
