How gdb accesses another process variable

[CygwinUser]

Hi,

I see the feature provided by gdb, that we can set a variable (using set
command) for a running process
through gdb. Can any one tell me how can gdb (as a process) could access the
variables of other process.
I guess its more of a OS related doubt. Please let me know. Thanks.
