ebbcharmutex Directory Reference
Directory dependency graph for ebbcharmutex:


file  ebbcharmutex.c
 An introductory character driver to support the second article of my series on Linux loadable kernel module (LKM) development. This module maps to /dev/ebbchar and comes with a helper C program that can be run in Linux user space to communicate with this the LKM. This version has mutex locks to deal with synchronization problems.
file  testebbcharmutex.c
 A Linux user space program that communicates with the ebbchar.c LKM. It passes a string to the LKM and reads the response from the LKM. For this example to work the device must be called /dev/ebbchar.
