nng_aio_set_input - set input parameter
Contents
Description
The nng_aio_set_input() function sets the input parameter at index to param for the asynchronous
operation associated with aio.
The type and semantics of input parameters are determined by specific operations; the caller must supply
appropriate inputs for the operation to be performed.
The valid values of index range from zero (0) to three (3), as no operation currently defined can accept
more than four parameters. (This limit could increase in the future.)
Note
If the index does not correspond to a defined input for the operation, then this function will have
no effect.
Important
It is an error to call this function while the aio is currently in use by an active asynchronous
operation.
An input parameter set with this function may be retrieved later with the nng_aio_get_input() function.
Errors
None.
Name
