Writes memory to the X.25 Interface Co-Processor/2 from a user buffer.
Note: Only a process that has opened the device for diagnostics can issue this call.
The X25_DIAG_MEM_WRITE x25sioctl operation writes memory to the X.25 Interface Co-Processor/2 from a user buffer. For this operation, the arg parameter points to a x25_diag_mem structure. This parameter provides the following:
The write can cover more than one page of card memory.
The X25_DIAG_MEM_WRITE operation can be called from the process environment only.
A return code of -1 indicates an unsuccessful operation. If -1 is returned, the kernel sets the errno global variable to one of the following values:
| EACCES | The channel was not opened in diagnostic mode. |
| ENXIO | The operation attempted to read a card that was not configured. |
The X25_DIAG_MEM_WRITE operation functions with an X.25 Interface Co-Processor/2 that has been correctly configured for use on a qualified network. Consult adapter specifications for more information on configuring the adapter and network qualifications.
The X25_DIAG_IO_READ x25sioctl operation, X25_DIAG_IO_WRITE x25sioctl operation, X25_DIAG_MEM_READ x25sioctl operation, X25_DIAG_TASK x25sioctl operation.
