Variable Documentation

AFPobj

AFPObj* AFPobj = NULL

We generally pass this from afp_over_dsi to all afp_* funcs, so it should already be available everywhere. Unfortunately some funcs (eg acltoownermode) need acces to it but are deeply nested in the function chain with the caller already without acces to it. Changing this would require adding a reference to the caller which itself might be called in many places (eg acltoownermode is called from accessmode). The only sane way out is providing a copy of it here:

debug_request

volatile sig_atomic_t debug_request = 0

static

recon_jmp

sigjmp_buf recon_jmp

static

reload_request

volatile int reload_request = 0

replaycache

rc_elem_t replaycache[REPLAYCACHE_SIZE]

static

AFP replay cache:

• fix sized array
• indexed just by taking DSIreqID mod REPLAYCACHE_SIZE
