binaryninja.binaryview.BinaryWriter¶

class BinaryWriter(view, endian=None)[source]¶

class BinaryWriter is a convenience class for writing binary data.

BinaryWriter can be instantiated as follows and the rest of the document will start from this context

>>> from binaryninja import *
>>> bv = BinaryViewType['Mach-O'].open("/bin/ls")
>>> br = BinaryReader(bv)
>>> bw = BinaryWriter(bv)
>>>

Or using the optional endian parameter

>>> from binaryninja import *
>>> br = BinaryReader(bv, Endianness.BigEndian)
>>> bw = BinaryWriter(bv, Endianness.BigEndian)
>>>

__init__(view, endian=None)[source]¶: x.__init__(…) initializes x; see help(type(x)) for signature

Methods

`__init__`(view[, endian])	x.__init__(…) initializes x; see help(type(x)) for signature
`seek`(offset)	`seek` update internal offset to `offset`.
`seek_relative`(offset)	`seek_relative` updates the internal offset by `offset`.
`write`(value)	`write` writes `len(value)` bytes to the internal offset, without regard to endianness.
`write16`(value)	`write16` writes the lowest order two bytes from the integer `value` to the current offset, using internal endianness.
`write16be`(value)	`write16be` writes the lowest order two bytes from the big endian integer `value` to the current offset.
`write16le`(value)	`write16le` writes the lowest order two bytes from the little endian integer `value` to the current offset.
`write32`(value)	`write32` writes the lowest order four bytes from the integer `value` to the current offset, using internal endianness.
`write32be`(value)	`write32be` writes the lowest order four bytes from the big endian integer `value` to the current offset.
`write32le`(value)	`write32le` writes the lowest order four bytes from the little endian integer `value` to the current offset.
`write64`(value)	`write64` writes the lowest order eight bytes from the integer `value` to the current offset, using internal endianness.
`write64be`(value)	`write64be` writes the lowest order eight bytes from the big endian integer `value` to the current offset.
`write64le`(value)	`write64le` writes the lowest order eight bytes from the little endian integer `value` to the current offset.
`write8`(value)	`write8` lowest order byte from the integer `value` to the current offset.

Attributes

`endianness`	The Endianness to written data.
`offset`	The current write offset (read/write).
