Does GDB has 'quiet mode', and does GDB has APIs for writing log

Hi all:

I've modified GDB to support set breakpoints automatically according
to a file containing all the EIP/RIP address that will be checked (a
litter bit like `gdb -x file` command). But, the amount of breakpoints
is too large, at least 10000, so I do not want to get any output like
`Breakpoint 1, fun2 () at main.c:35` on my screen, I want GDB to be
quiet at this time. Does GDB has something like `quiet mode`? Or, can
I redirect these hints into a file?

And, I want to write log when GDB is in `quiet mode`, does GDB has any
APIs to support log?

Thanks!

BR.
