Stops the compilier (correctly) complaining:
lib/test_shm.c: In function ‘main’:
lib/test_shm.c:65:23: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 2 has type ‘int’ [-Wformat=]
65 | printf("SHMID: %llx\n", shm_id);
| ~~~^ ~~~~~~
| | |
| | int
| long long unsigned int
shm_id is an int which is what shmget() returns.
Strangely pmap has always scanned this in as a llx even though the maps
"inode" column is the same number that shmget() returns.

Created a test process test_shm that allocates a shared memory
segment and prints the segment ID. pmap testsuite runs pmap to
check that the segment is found.
The value returned by shmget() is the same value that is printed
in the fifth column /proc/<PID>/maps
