This string is -// used internally by Breakpad to -// prefix user-supplied parameter -// names so those can be sent to the -// server without leaking Breakpad's -// internal values. - -// Returns a new BreakpadRef object on success, NULL otherwise. -BreakpadRef BreakpadCreate(NSDictionary *parameters); - -// Uninstall and release the data associated with |ref|. -void BreakpadRelease(BreakpadRef ref); - -// User defined key and value string storage.

Note that -// the string is converted to UTF8 before truncation, so any multibyte -// character that straddles the 255(256 - 1 for terminator) byte limit -// will be mangled. -// -// A maximum number of 64 key/value pairs are supported.
