Python strings are used to hold the data representing the C struct and also as format strings to describe the layout of data in the C struct. 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; 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. s0.1iĸĸĸĸ(tStructterroridcCs;ttƒtjotiƒnt|ƒ}|t|<|S(N(tlent_cachet _MAXCACHEtclearR(tfmtts((s/usr/lib/python2.5/struct.pyt_compile#s   cCs7yt|}Wntj ot|ƒ}nX|iS(st Return size of C struct described by format string fmt.
