OpenRCE IDA SDK >> patch_byte
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: Related: get_byte, get_many_bytes, patch_byte, patch_many_bytes Note: You must be logged in to add notes to the IDA SDK reference manual. |
