### 3.2.146 shmread

    shmread ID, VAR, POS, SIZE

This function reads from the shared memory segment `ID` starting at position `POS` for size `SIZE` (by attaching to it, copying out, and detaching from it). `VAR` must be a variable that will hold the data read. The function returns true if successful, or false if there is an error. On error, it puts the error code into $!. This function is available only on machines supporting System V IPC.
