3.1.4.1.8.1 DEVMODE_CONTAINER Parameters

  • 發行項

pDevMode: This parameter is a pointer to a DEVMODE_CONTAINER (section 2.2.1.2.1) structure.

pDevModeContainer: This parameter is synonymous with pDevMode.

The individual method sections include the following parameter validation steps by reference:

  • If the pDevModeContainer parameter is declared with the "unique" IDL attribute, and its value is NULL, the server SHOULD skip the validation steps and assume validation success.

  • If the pDevModeContainer parameter is not declared with the "unique" IDL attribute, the server MAY verify that its value is not NULL.<257>

  • The server SHOULD verify that the pDevMode member of the DEVMODE_CONTAINER that is pointed to by pDevModeContainer is NULL, or that the _DEVMODE (section 2.2.2.1) structure that is pointed to by the pDevMode member is valid, which means that the total size specified in _DEVMODE MUST be less than or equal to the number of bytes specified by the value of the cbBuf member of the DEVMODE_CONTAINER.

  • The server SHOULD verify that the dmSize and dmDriverExtra members of the _DEVMODE structure comply with the constraints defined in section 2.2.2.1, and that the sum of their values is not larger than the cbBuf member of the DEVMODE_CONTAINER.

    Note: The server uses the printer driver associated with a print queue to validate all other _DEVMODE members. Incorrect settings for these other members are silently corrected by the printer driver. Therefore, the print client SHOULD obtain a valid _DEVMODE from the printer driver or print queue to use as template for the DEVMODE_CONTAINER parameter. The client SHOULD modify selected fields only as necessary and as indicated by the printer driver capabilities that are returned by a local call to the printer driver.

Unless noted otherwise, if any of the preceding validation steps fail, the server SHOULD return ERROR_INVALID_PARAMETER.
