| 178 | * -------------------------- |
| 179 | * |
| 180 | * Start-off w/ empty buffer of specific size SHM_SIZ |
| 181 | * Start filling it up w/ messages. I use '\0' as separator to break up messages. |
| 182 | * This is also very handy since we can do printf on message. |
| 183 | * |
| 184 | * Once the buffer is full we need to get rid of the first message in buffer and |
| 185 | * insert the new message. (Note: if the message being added is >1 message then |
| 186 | * we will need to "remove" >1 old message from the buffer). The way this is done |
| 187 | * is the following: |
| 188 | * When we reach the end of the buffer we set a mark and start from the beginning. |
| 189 | * Now what about the beginning and end of the buffer? Well we have the "head" |
| 190 | * index/pointer which is the starting point for the messages and we have "tail" |
| 191 | * index/pointer which is the ending point for the messages. When we "display" the |
| 192 | * messages we start from the beginning and continue until we reach "tail". If we |
| 193 | * reach end of buffer, then we just start from the beginning (offset 0). "head" and |
| 194 | * "tail" are actually offsets from the beginning of the buffer. |
| 195 | * |
| 196 | * Note: This algorithm uses Linux IPC mechanism w/ shared memory and semaphores to provide |
| 197 | * a threasafe way of handling shared memory operations. |
