3.1.4.1.8.4 FORM_CONTAINER Parameters
pFormInfoContainer: This parameter is a pointer to a FORM_CONTAINER (section 2.2.1.2.4) structure that specifies form information.
The individual method sections include the following parameter validation steps by reference:
If the pFormInfoContainer parameter is declared with the "unique" IDL attribute, and its value is NULL, skip the validation steps and assume validation success.
Verify that pFormInfoContainer points to a FORM_CONTAINER that specifies an appropriate level as defined in the referring method definition. If that verification fails, return ERROR_INVALID_LEVEL.
Verify that all members of the FORM_CONTAINER structure comply with the constraints defined in section 2.2.1.2.4.
Unless noted otherwise, if any of the preceding validation steps fail, return ERROR_INVALID_PARAMETER.
