* Symbolic values are read from stdin using standard libc calls.
|
|
* Program checks if a binary packed integer at the input is 0x41 or less.
|
|
*
|
|
* Compile with :
|
|
* $ gcc -static -Os basic.c -o basic
|
|
*
|
|
* Analyze it with:
|
|
* $ manticore basic
|
|
*
|
|
* - By default manticore will consider all input of stdin symbolic
|
|
*
|
|
* Expected output:
|
|
* $ manticore basic

|
|
*
|
|
* Look at ./mcore_IJ2sPb for results, you will find something like this:
|
|
* $ hexdump -C test_00000001.stdin
|
|
* 00000000 00 80 00 20 |... |
|
|
*
|
|
* $ hexdump -C test_00000002.stdin
|
|
* 00000000 41 00 00 00 |A...|
|
|
*
|
|
* You can try out the values like this:
|
|
*
|
|
* $ printf "\x00\x80\x00\x20" | ./basic
|
|
* Message: It is greater than 0x41
|
|
*
|
|
* $ printf "\x41\x00\x00\x00" | ../basic
|
|
* Message: It is smaller or equal than 0x41
