A parameter struct for the functions sc_scda_fopen_write and sc_scda_fopen_read.
The struct may be extended in the future.
The option struct is a collective structure. If the options structure that is passed to a function is not the same on all processes, the whole following scda workflow has undefined behavior.
| unsigned sc_scda_params::fuzzy_everyn |
In average every n-th possible error origin returns a fuzzy error.
There may be multiple possible error origins in one top-level scda function. We return for each possible error origin a random error with the empirical probability of 1 / fuzzy_everyn but only if the respective possible error origin did not already cause an error without the fuzzy error return. In such a case, the actual error is returned. 0 means that there are no fuzzy error returns.
| sc_rand_state_t sc_scda_params::fuzzy_seed |
The seed for the fuzzy error return.
This value is ignored if fuzzy_everyn == 0. When in doubt use fuzzy_seed = 0.
| int sc_scda_params::log_level |
The log level for the scda functions.
The possible values are documented in sc.h; cf. SC_LP_* macros.
