129be006 90 * 'S' it just appends the rest of the string (accept optional quote)
361127df
MA
91 * 'O' option string of the form NAME=VALUE,...
92 * parsed according to QemuOptsList given by its name
93 * Example: 'device:O' uses qemu_device_opts.

99 * value is multiplied by 2^20 (think Mebibyte)
dbc0c67f 100 * 'o' octets (aka bytes)
5e00984a
KW
101 * user mode accepts an optional E, e, P, p, T, t, G, g, M, m,

107 * which divides the value by 1e3, 1e6, 1e9, respectively
9307c4c1
FB
108 * '/' optional gdb-like print format (like "/10x")
109 *
fb46660e
LC
110 * '?' optional type (for all types, except '/')
111 * '.' other form of optional type (for 'i' and 'l')
