hi all:
I want to use snprintf for collecting debug message and print it later.
But I found :
1. when I add "\n" as below, the buffer will be cleared, that means
the "irq status" will put at the head of Buffer instead of at the end
of "ehci work".
Size -= snprintf (Buffer , Size,"ehci_work\n");
Size -= snprintf (Buffer , Size,"irq status 0x%x\n",status);
is it possible to add "\n" in the buffer, but will will not reset the buffer?
2. instead of snprintf, is there any better idea for saving debug
message and show it out later?
