Can someone explain the structure of a Pid (Process Identifier) in Erlang?
Printed process ids < A.B.C > are composed of 6: A, the node number (0 is the local node, an arbitrary number for a remote node) B, the first 15 bits of the process number (an index into the process table) 7 C, bits 16-18 of the process number (the same process number as B) 7 Internally, the process number is 28 bits wide on the 32 bit emulator. The odd definition of B and C comes from R9B and ear
pid_to_list() changing value of pid?
I have code like: PID = spawn_link(DistrNode, ...... io:format("~p debug1 ~n",[PID]), io:format("~p debug2 ~n",[pid_to_list(PID)]), and I get like: <10062.97.0> debug1 "<9453.97.0>" debug2 I want grab PID as string but not change value like it did above- what is happening here? I looked convert pid to atom, but no function there. I wanted to get "<10062.97.0>" EDIT it spawn_link() not spawn() this
