install_user_defined_prefix

summary: insert information into listing prefixes

description:

By default, disassembly line prefixes contain segment + address information (e.g., ‘.text:08047718’), but it is possible to “inject” other bits of information in there, thanks to the ida_lines.user_defined_prefix_t helper type.

get_user_defined_prefix(ea, insn, lnnum, indent, line)

This callback must be overridden by the derived class.

Parameters:

  • ea – the current address

  • insn – the current instruction. if the current item is not an instruction, then insn.itype is zero.

  • lnnum – number of the current line (each address may have several listing lines for it). 0 means the very first line for the current address.

  • indent – see explanations for gen_printf()

  • line – the line to be generated. the line usually contains color tags. this argument can be examined to decide whether to generate the prefix.
