Function Documentation

void c1_post (  void *  data  )

The function that will be called by the simulator when a data period is finished. Parameters: data  The process' data. Definition at line 178 of file rk_stubby.c. References c1_data, clock_gettime, and verbosity.

rk_stub_precall_retval_t c1_pre (  void *  data  )  [static]

The function that will be called by the simulator when a new data period is started. Parameters: data  The process' data. Returns: RKSP_OK if drop_all == false and drop_behind == false or the process is making its deadlines. Otherwise, it returns RKSP_DROP. Definition at line 122 of file rk_stubby.c. References c1_data, clock_gettime, cra, drop_all, drop_behind, cpu_reserve_attr::period, rk_stub_precall_retval_t, RKSP_DROP, RKSP_OK, timespec_to_microsec(), and verbosity.

Here is the call graph for this function:

int parse_boolean (  char *  str  )  [static]

Interpret a string as a boolean value. Parameters: str  The string to interpret. Returns: True if the string case insensitively matches one of the following values: true, yes, 1, on. Otherwise, the function returns false. Definition at line 85 of file rk_stubby.c.
