+
+Compute the 32-bit CRC of @var{buf} which has length @var{len}. The
+starting value is @var{init}; this may be used to compute the CRC of
+data split across multiple buffers by passing the return value of each
+call as the @var{init} parameter of the next.
+
+This is intended to match the CRC used by the @command{gdb} remote
+protocol for the @samp{qCRC} command. In order to get the same
+results as gdb for a block of data, you must pass the first CRC
+parameter as @code{0xffffffff}.
+
+This CRC can be specified as:
+
+ Width : 32
+ Poly : 0x04c11db7
+ Init : parameter, typically 0xffffffff
+ RefIn : false
+ RefOut : false
+ XorOut : 0
+
+This differs from the "standard" CRC-32 algorithm in that the values
+are not reflected, and there is no final XOR value. These differences
