Returns the value of the one or more specified attributes of an application instance. The instance is specified by its numeric instanceID that uniquely identifies it in the remote EDMdatabase. The attributes are identified by their names. Optionally, this function may be used to determine if one or more attributes of an instance has been assigned values or are unset.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiAppInstance	instance	A numeric instanceID that uniquely identifies the instance of interest in the remote EDMdatabase
SdaiVersion	version	The version of the edmModel to apply this function call on. The <version> parameter is a numeric sequence number counting from one by increments of one for each new model version that is created. A zero model version number means the current version.
SdaiInteger	nAttrs	The number of attributes for which to to assign values.
SdaiString	attributeName	A buffer of string pointers. Each string pointer represents an attribute name for which to read its value.
SdaiSelect	value	A buffer of pre-allocated tSdaiSelect structures. Each select structure will receive one attribute value.
SdaiOptions	options	See description of available options below. Options may be joined by using bitwise OR operator
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value

Error rendering macro 'excerpt-include' : User 'null' does not have permission to view the page 'US:_r_EDMInterface'.

Options

Option	Comment
GET_ATTRS	The function will return the attribute type and value in the <value> buffer.
TEST_ATTRS	The function will return a Boolean value for each of the attributes in the <attributeName> buffer. An sdaiTRUE value means the attribute has been assigned a value. An sdaiFALSE value indicate that the attribute is unset.
