mem command and set command

hello all,

Executing the following GDB commands:
 
mem 0x0 0x100 16
set *0x0=0x12345678

I found the 3rd parameter of write_memory (CORE_ADDR
memaddr, const 
bfd_byte *myaddr, int len) is always 4.
I think the length should be 2 because "mem 0x0 0x100
16" has set memory 
width to 16.
Does "mem" command affect write memory operation?

No.  The width appears to be unused.  I just use set 
0 =
0x1234 when I want to generate a 16-bit write.
