Return code of dcmsnd is zero when errors occur

[Andreas Borg]

Hello,

we use dcmsnd in a shell script and check the return code (aka exit status / exit code) to see if an error occured (in which case the images will be sent again), with code like this:

 

dcmsnd ..

if [ "$?" -ne "0" ]; then

  # error handling code goes here

fi

For very critical errors (i.e. no network connection) this works as expected. However, in some cases, dcmsnd returns a zero status even if something goes wrong, for example, if some, but not all images were transferred successfully. Another example this case (sensitive information removed):

In this case, the script believes the transmission was successful and continues. Is this a bug or intended behaviour?

Best regards,

Andreas

This is intended behaviour. dcmsnd will exit with code not 0 only if it fails to establish a connection with the Store SCP, otherwise it prints out info for each request/response transaction - even if the response is an error code.
