Description of the 'p' command in HyperDbg. |
p
pr
p
p [Count (hex)]
pr
pr [Count (hex)]
Executes a single instruction (step-over) and optionally displays the resulting values of all registers and flags.
[Count (hex)] (optional)
Count of step(s), or how many times perform the stepping operation. If you don't set this argument, then by default, the Count is 1.
If you want to step-over one instruction.

fffff801`63a12b00 F6 44 24 10 01 test byte ptr ss:[rsp+0x10], 0x01To step-over the instruction, you need to use the following function in libhyperdbg:
BOOLEAN
hyperdbg_u_stepping_step_over();
This command will set a trap flag in debuggee and continue all the cores. After executing one instruction, it halts the debuggee again.
If the target instruction is a call instruction, it configures the first hardware debug register breakpoint to the instruction after that call. After that, it continues the debuggee and waits for the call to be returned and the next instruction (after the call) to be executed.
All cores and threads (except the currently executing thread) find a chance to be executed between each step in this type of stepping.
If you load symbols and you don't want to see function names, you turn addressconversion off in the 'settings' command.
