X.25 Communications Library (libx25s.a)
int x25_interrupt(conn_id, cb_int) int conn_id: struct cb_int_data_struct *cb_int;
The x25_interrupt subroutine sends an interrupt message. Control is returned to the application when the message has been received by the adapter.
| conn_id | Contains the connection identifier of the call. |
| cb_int | Contains a pointer to the cb_int_data_struct structure, which contains the interrupt data. |
If successful, the x25_interrupt subroutine returns a value of 0. If an error occurs, the x25_interrupt subroutine returns a value of -1 and sets the x25_errno global variable to one of the error codes shown below.
On failure, the x25_errno global variable is set to one of the following:
If the x25_errno global variable is set to a X25SYSERR value, the errno global variable is set to one of the following values:
The following code statement ends an interrupt:
struct cb_int_struct int_data;
int_data.flags = X25FLG_INT_DATA;
int_data.data_len = 20;
int_data.int_data = "This is an interrupt";
rc = x25_interrupt(conn_id,&int_data);
if (rc < 0)
(void)printf("Error %d from x25_interrupt.",x25_errno);
