Error Reporting by API S/W Library Function – Point 4
At point 4, execution will be returned to the original API S/W Library function issuing the
command. The API S/W Library function will receive a status code returned by ApiIo. If the
status code is an error code (which has already been interpreted by ApiIo) then upon completion
of the API S/W Library function where final error reporting is performed, an error message
“ERROR in function “ message as shown in Figure 12.1-2 will occur with function name equal
to the calling API S/W Library function. Since the error code is reserved for the Target S/W
errors, it will be interpreted as (unknown) by the API S/W Library function.
The following example in Figure 12.1-7 shows the error messages generated by ApiIo and the
API S/W Library function when the Target S/W detected an error. The following error
messages occurred when ApiCmdCalCplCon was issued after the Target module had been
closed (ApiClose).
