C: Parse empty tokens from a string with strtok

Question

My application produces strings like the one below. I need to parse values between the separator into individual values.

2342|2sd45|dswer|2342||5523|||3654|         


        

Answer 1

Below is the solution that is working for me now. Thanks to all of you who responded.

I am using LoadRunner. Hence, some unfamiliar commands, but I believe the flow can be understood easily enough.

char strAccInfo[1024], *p2;
int iLoop;

Action() {  //This value would come from the wrsp call in the actual script.
    lr_save_string("323|90||95|95|null|80|50|105|100|45","test_Param");

    //Store the parameter into a string - saves memory. 
    strcpy(strAccInfo,lr_eval_string("{test_Param}"));
    //Get the first instance of the separator "|" in the string
    p2 = (char *) strchr(strAccInfo,'|');

    //Start a loop - Set the max loop value to more than max expected.
    for (iLoop = 1;iLoop<200;iLoop++) { 

        //Save parameter names in sequence.
        lr_param_sprintf("Param_Name","Parameter_%d",iLoop);

        //Get the first instance of the separator "|" in the string (within the loop).
        p2 = (char *) strchr(strAccInfo,'|');           

        //Save the value for the parameters in sequence. 
        lr_save_var(strAccInfo,p2 - strAccInfo,0,lr_eval_string("{Param_Name}"));   

        //Save string after the first instance of p2, as strAccInfo - for looping.
        strcpy(strAccInfo,p2+1);

        //Start conditional loop for checking for last value in the string.
        if (strchr(strAccInfo,'|')==NULL) {
            lr_param_sprintf("Param_Name","Parameter_%d",iLoop+1);
            lr_save_string(strAccInfo,lr_eval_string("{Param_Name}"));
            iLoop = 200;    
        }
    }
}
