Problem understanding a line in a code

60 New Member
Hello Team,

I extracted this line from a code and I have problems understanding it. I dont understand the use of ' ' and of << on this line. Can someone explain to me.

#define CLUSTERS_DATAID ((homer_uint64)'CLUS' << 32 | (homer_uint64)'TERS')

<< means left shifting by 32 bits
