hbutils.binary.int¶

CSignedIntType¶

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

Overview:: Signed int type.

__init__(size: int)[source]¶

Constructor of CSignedIntType.

Parameters:: size – Size of the type.

read(file: BinaryIO) → int[source]¶

Read signed int value.

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

property size¶: Size of the given type.

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

Write signed int value to binary IO object.

Parameters:

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

c_short¶

hbutils.binary.int.c_short = <hbutils.binary.int.CSignedIntType object>¶: Alias for c_int16.

c_int¶

hbutils.binary.int.c_int = <hbutils.binary.int.CSignedIntType object>¶: Alias for c_int32 (in 64-bits OS).

Note

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

Note

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

c_longlong¶

hbutils.binary.int.c_longlong = <hbutils.binary.int.CSignedIntType object>¶: Alias for c_int64 (in 64-bits OS).

Note

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