Reef is an IDAPython plugin for finding cross references (Xrefs) from a function. Each Xref is represented by direction, type, addres and disassembly text, as in the IDA builtin Xref to functionality.

#include <stdio.h>

void bar()
{
	printf("hello from bar\n");
}

void foo()
{
	wprintf(L"hello from foo\n");
	bar();
}

void foo2()
{
	wprintf(L"hello from foo2\n");
	bar();
}

void main()
{
	printf("hello from main\n");
	foo();
	foo2();

	getchar();
}

I put the cursor on the main function and hit Shift+x. We get the following Reef output:

Notice that each Xref is clickable ! :)

• IDA (Hex Rays Interactive Disassembler) version >= 6.1 with IDAPython

1. Copy src/Reef.py file to the plugins directory of IDA (%IDAPATH%\plugins) and restart IDA.

2. You are ready to go :)

load your favourite binary with IDA. To find Xrefs from the current function, focus on any line in the function disassembly and hit Shift+x.

Reef can also be found in Edit/Plguins/Reef menu.
