hbutils.binary.uint¶

CUnsignedIntType¶

class hbutils.binary.uint.CUnsignedIntType(size: int)[source]¶

Overview:: Unsigned int type.

__init__(size: int)[source]¶

Constructor of CUnsignedIntType.

Parameters:: size – Size of the type.

read(file: BinaryIO) → int[source]¶

Read unsigned int value.

Parameters:: file – Binary file, io.BytesIO is supported as well.
Returns:: Unsigned int value.

property size¶: Size of the given type.

write(file: BinaryIO, val: int)[source]¶

Write unsigned int value to binary IO object.

Parameters:

file – Binary file, io.BytesIO is supported as well.
val – Unsigned int value to write.

c_byte¶

hbutils.binary.uint.c_byte = <hbutils.binary.uint.CUnsignedIntType object>¶: Alias for c_uint8.

c_ushort¶

hbutils.binary.uint.c_ushort = <hbutils.binary.uint.CUnsignedIntType object>¶: Alias for c_uint16.

c_uint¶

hbutils.binary.uint.c_uint = <hbutils.binary.uint.CUnsignedIntType object>¶: Alias for c_uint32 (in 64-bits OS).

Note

Note

Size of c_ulong is the same as that in C language, which mainly depends on CPU and OS.

c_ulonglong¶

hbutils.binary.uint.c_ulonglong = <hbutils.binary.uint.CUnsignedIntType object>¶: Alias for c_uint64 (in 64-bits OS).

Note

Size of c_ulonglong is the same as that in C language, which mainly depends on CPU and OS.
