Category: Data

idaman void ida_export
patch_byte(ea_t ea, ulong x)
Replace the byte at ea with x. The original byte is saved to the IDA database, and can be retrieved using get_original_byte() (see bytes.hpp). To not save the original byte, use put_byte(ea_t ea, ulong x) instead. Also available for working with larger chunks is put_word(), put_long() and put_qword(). Use put_many_bytes() for working with multiple byte chunks.

Examples:
#include <kernwin.hpp> // For get_screen_ea()
#include <bytes.hpp>

// Get the flags for the byte at the cursor position.
flags_t flags = getFlags(get_screen_ea());

// Replace the instruction at the cursor position with a NOP instruction (0x90).
// Unless used carefully, your executable will probably not work correctly after this :-)
if (isCode(flags))
    patch_byte(get_screen_ea(), 0x90);
