NAME
struct
FILE
/opt/swe/tools/ext/gnu/python-2.7.3/lib/python2.7/struct.py
DESCRIPTION
Functions to convert between Python values and C structs represented
as Python strings. It uses format strings (explained below) as compact
descriptions of the lay-out of the C structs and the intended conversion
to/from Python values.
The optional first format char indicates byte order, size and alignment:
@: native order, size & alignment (default)
=: native order, std. size & alignment
<: little-endian, std. size & alignment
>: big-endian, std. size & alignment
!: same as >
The remaining chars indicate types of args and must match exactly;
these can be preceded by a decimal repeat count:
x: pad byte (no data); c:char; b:signed byte; B:unsigned byte;
?: _Bool (requires C99; if not available, char is used instead)
h:short; H:unsigned short; i:int; I:unsigned int;
l:long; L:unsigned long; f:float; d:double.
Special cases (preceding decimal count indicates length):
s:string (array of char); p: pascal string (with count byte).
Special case (only available in native format):
P:an integer type that is wide enough to hold a pointer.
Special case (not in native mode unless 'long long'in platform C):
q:long long; Q:unsigned long long
Whitespace between formats is ignored.
The variable struct.error is an exception raised on errors.

FUNCTIONS
calcsize(...)
Return size of C struct described by format string fmt.
pack(...)
Return string containing values v1, v2, ... packed according to fmt.
pack_into(...)
Pack the values v1, v2, ... according to fmt.
Write the packed bytes into the writable buffer buf starting at offset.
unpack(...)
Unpack the string containing packed C structure data, according to fmt.
Requires len(string) == calcsize(fmt).
unpack_from(...)
Unpack the buffer, containing packed C structure data, according to
fmt, starting at offset. Requires len(buffer[offset:]) >= calcsize(fmt).
