API Function Descriptions

RscIoCheck [RSCCHK]

The RscIoCheck function looks for the completion of an outstanding nowaited I/O

issued on the session identified by ulSessionHandle and retrieves the reply if the

operation is complete. Upon successful completion of the function, the field referenced

by puReplySize contains the actual number of characters stored in the buffer

referenced by pvReplyBuffer.

);

ulConnectionHandle

The handle of an existing connection created through the RscConnect function

call.

ulSessionHandle

The handle of an existing session created through the RscBeginSession function

call.

pnIoHandle

A pointer to the field that contains the handle of the I/O to be checked or the value

RSC_IO_CHECK_ALL. If the constant RSC_IO_CHECK_ALL is specified,

RscIoCheck places the handle of the completed I/O in the field referenced by

pnIoHandle.

pvReplyBuffer

A pointer to the buffer that receives the data from the reply upon successful

completion of RscIoCheck.

puReplySize

A pointer to the field that receives the size of the reply. This field should contain the

size of the buffer referenced by pvReplyBuffer. Upon successful completion of this

function, this field receives the actual number of characters stored in

pvReplyBuffer. This parameter should point to a buffer of the size puReplySize.
