Buffer to hold the session information
On return from a successful call, the buffer will contain the following information for each active session:
Byte 1: one character session ID
Byte 2-9: long session ID.  QWS3270 does not use a long session name so these bytes will always be 0

buf_size

Buffer size. It must be defined as minimum 12*(number of active sessions) characters. It will contain the number of active 3270 screen sessions on return.

Return Code

JGS_PARAMETERERROR

Invalid buffer size

JGS_SYSERROR

The function failed due to a system error

Remarks

The return value of buf_size is set when the return code is JGS_OK or JGS_PARAMETERERROR.  If you receive a return code of 2, use buf_size to recalculate the necessary value for the size of buffer (and the value for buf_size on the call).
