What is "inferior process" ??

[Zheng Jian-Ming]

Hi,

I am reading the GDB's source codes, and see the word "inferior process"
many times (e.g. in gdb/inferior.h). But i don't understand what this 
really means.

Is "inferior process" a child process or a parent process, or something
else?

BTW, i only see function lin_lwp_resume() in gdb/lin-lwp.c, and wonder 
how to call/use this function.

Thank you.
