netno [in]
stno [in]
offset [in]
size [in]
data [in]
timeout [in]
■Return value
Value
MMC_OK
MMERR_ARGUMENT_0
=1 to 9: Argument location

■Point
• Specify the byte size of the write data in even number.
• When MMC_INFINITE is designated as the timeout time, timeout is not checked. Instead, this function infinitely waits for
completion of the SLMP communication process.
• It is recommended to set 500 ms or more for the timeout time.
