1114  *
1115  * PARAMS
1116  *  lpFile   [I] The file to find the association for. This must refer to
1117  *               an existing file otherwise FindExecutable fails and returns
1118  *               SE_ERR_FNF.
1119  *  lpResult [O] Points to a buffer into which the executable path is
1120  *               copied. This parameter must not be NULL otherwise
1121  *               FindExecutable() segfaults. The buffer must be of size at
1122  *               least MAX_PATH characters.
1123  *
1124  * RETURNS
1125  *  A value greater than 32 on success, less than or equal to 32 otherwise.
1126  *  See the SE_ERR_* constants.
1127  *
1128  * NOTES
1129  *  On Windows XP and 2003, FindExecutable() seems to first convert the
1130  *  filename into 8.3 format, thus taking into account only the first three
1131  *  characters of the extension, and expects to find an association for those.
1132  *  However other Windows versions behave sanely.
