yt_initialize – Initialize

yt_initialize

int yt_initialize(int argc, char *argv[], const yt_param_libyt *param_libyt)

• Usage: Initialize libyt and import your Python script. This API should only be called once.

• Return: YT_SUCCESS or YT_FAIL.

yt_param_libyt

• yt_verbose verbose (Default=YT_VERBOSE_WARNING)

  • Usage: Set the log message level.

  • Valid Value for yt_verbose:

    • YT_VERBOSE_OFF: Turn off log message.

    • YT_VERBOSE_INFO: Output log level below or equal to info.

    • YT_VERBOSE_WARNING: Output log level below or equal to warning.

    • YT_VERBOSE_DEBUG: Output all log.

• const char* script (Default=yt_inline_script)

  • Usage: Your Python script name. Do NOT contain .py. Make it a unique name that is different from python module name.

  Please make sure the lifetime of script covers the whole in situ analysis process.

• long counter (Default=0)

  • Usage: Number of rounds doing inline-analysis, may be useful in restart.

• bool check_data (Default=true)

  • Usage: Check the input data (see Checking Input Data), if it is true. Set this to false after you have successfully implemented libyt.

Example

int main(int argc, char *argv[]){
    ...
    yt_param_libyt param_libyt;
    param_libyt.verbose = YT_VERBOSE_INFO;
    param_libyt.script  = "inline_script";
    param_libyt.check_data = false;
	
    /* Initialize libyt, should only be called once. */
    if( yt_initialize( argc, argv, &param_libyt ) != YT_SUCCESS ){
        // error message
        exit( EXIT_FAILURE );
    }
    ...
}
