9307c4c1 67 * 's' string (accept optional quote)
361127df
MA		 68 * 'O' option string of the form NAME=VALUE,...
69 * parsed according to QemuOptsList given by its name

FB		 73 * 'i' 32 bit integer
74 * 'l' target long (32 or 64 bit)
9fec543f
MA		 75 * 'M' just like 'l', except in user mode the value is
76 * multiplied by 2^20 (think Mebibyte)
ee9545da 77 * 'f' double
3350a4dd
MA		 78 * user mode accepts an optional G, g, M, m, K, k suffix,
79 * which multiplies the value by 2^30 for suffixes G and
80 * g, 2^20 for M and m, 2^10 for K and k
fccfb11e
MA		 81 * 'T' double
82 * user mode accepts an optional ms, us, ns suffix,
83 * which divides the value by 1e3, 1e6, 1e9, respectively
9307c4c1
FB		 84 * '/' optional gdb-like print format (like "/10x")
85 *
fb46660e
LC		 86 * '?' optional type (for all types, except '/')
87 * '.' other form of optional type (for 'i' and 'l')
942cd1f2
