char *filename = "c:\\myfilename.txt";
long file_stream;
vuser_init()
{
if ((file_stream = fopen(filename, "a+")) == NULL) //open file in append mode
{
lr_error_message ("Cannot open %s", filename);
return -1;
}
fprintf (file_stream, "%s\n", lr_eval_string("THE PARAMETER IS :{Parameter}")); //Parameter is parameter name to be written in a file
Return 0;
}
vuser_end()
{
fclose(file_stream);//dont forget to close file_stream in vuser_end scetion
return 0;
}
I understand how this writes to the txt file. I am trying to read from the text file and display the data in the output. here is my code.
ReplyDeletechar * filename ="c:\\myfilename.dat";
char fileLine[10];
char buffer[10];
long file_stream;
int count;
Action()
{
fopen(filename, "r");
if ((file_stream = fopen(filename, "r")) == NULL) {
lr_error_message ("Cannot open %s", filename);
return -1;
}
{while (feof(filename))
{fgets(fileLine[10], sizeof(10), filename);
break;
}
}
fclose(file_stream);
return 0;
}
I don't see output in the replay log:
Ending action vuser_init.
Running Vuser...
Starting iteration 1.
Starting action Action.
Ending action Action.
Ending iteration 1.
Ending Vuser...
Starting action vuser_end.
Ending action vuser_end.
Vuser Terminated
Figured out. The Code:
ReplyDeletechar * filename ="c:\\TeamNames.txt";
long file;
char names[10];
Action()
{
fopen(filename, "r");
if ((file = fopen(filename, "r")) == NULL) {
lr_error_message ("Cannot open %s", file);
return -1; }
while (!feof(file))
{
fgets(names, 10, file);
if (!feof(file)) //if not at the end of file print names
{
lr_output_message("%s",lr_eval_string(names));
}
}
fclose(file);
return 0;
}
Nice piece of code, exactly what i needed. Thanks!
ReplyDeleteHi,
ReplyDeleteI have used the same logic in my script to write parameter values into file. But I am getting C interpreter error message in Vuser_end at end of Iteraion. Can you please help me on this.
Thank you

ReplyDeleteHi, I want to save some value in to a note pad during a load test with HP PC. How can I do that when i dont have the access to LGs
ReplyDeleteHi All,
ReplyDeleteAs part of my requirement, I need to read the values from the DB and then write the data to a *.dat or *.txt file (within the Init section) and use the same file as a parameter in the same script instead of using the lr_db_getvalue since this carries an overhead on the CPU/memory consumption on the lg machine and also because we will not be able to allocate block if we use DB to get the values as ther could be a situation wherein the sane data is picked up by different users during the test. Any suggestion how to overcome this?
