1188 * for the default verb.
1189 *
1190 * PARAMS
1191 * lpFile [I] The file to find the association for. This must refer to
1192 * an existing file otherwise FindExecutable fails and returns
1193 * SE_ERR_FNF.
1194 * lpResult [O] Points to a buffer into which the executable path is
1195 * copied. This parameter must not be NULL otherwise
1196 * FindExecutable() segfaults. The buffer must be of size at
1197 * least MAX_PATH characters.
1198 *
1199 * RETURNS
1200 * A value greater than 32 on success, less than or equal to 32 otherwise.
1201 * See the SE_ERR_* constants.
1202 *
1203 * NOTES
1204 * On Windows XP and 2003, FindExecutable() seems to first convert the
1205 * filename into 8.3 format, thus taking into account only the first three
1206 * characters of the extension, and expects to find an association for those.
1207 * However other Windows versions behave sanely.
