[in] | inpParam | - a msParam of type DataObjInp_MS_T or a STR_MS_T which would be taken as msKeyValStr. msKeyValStr - This is the special msKeyValStr format of keyWd1=value1++++keyWd2=value2++++keyWd3=value3... If the keyWd is not specified (without the '=' char), the value is assumed to be the path of the data object("objPath") for backward compatibility. Valid keyWds are:
- "objPath" - the path of the data object to open.
- "rescName" - the resource of the data object to open.
- "replNum" - the replica number of the copy to open.
- "openFlags" - the open flags. valid open flags are: O_RDONLY, O_WRONLY, O_RDWR and O_TRUNC. These can be combined by concatenation, e.g. O_WRONLYO_TRUNC (without the '|' character). The default open flag is O_RDONLY.
|
[out] | outParam | - a msParam of type INT_MS_T containing the descriptor of the open. |
[in,out] | rei | - The RuleExecInfo structure that is automatically handled by the rule engine. The user does not include rei as a parameter in the rule invocation. |
