MEMADDR is an address within the target address space, MYADDR is an
address within GDB address-space where data is written to, LEN is
length of buffer, and WRITE indicates whether to read or write.
SECTIONS and SECTIONS_END defines a section table holding sections
from possibly multiple BFDs.
If SECTION_NAME is not NULL, only access sections with that same
name.
Result is a length:
0: We cannot handle this address and length.
> 0: We have handled N bytes starting at this address.
(If N == length, we did it all.) We might be able
to handle more bytes beyond this length, but no
promises.
< 0: We cannot handle this address, but if somebody
else handles (-N) bytes, we can start from there. */

/* Request to transfer up to LEN 8-bit bytes of the target sections
/* Read or write from mappable sections of BFD executable files.
Request to transfer up to LEN 8-bit bytes of the target sections
defined by SECTIONS and SECTIONS_END. The OFFSET specifies the
starting address.
If SECTION_NAME is not NULL, only access sections with that same
name.
Return the number of bytes actually transfered, or non-positive
when no data is available for the requested range.
Return the number of bytes actually transfered, or zero when no
data is available for the requested range.
This function is intended to be used from target_xfer_partial
implementations. See target_read and target_write for more
