[Valgrind-users] valgring whith JudyArray

[Salim S. <ssa...@ti...>]

Hello all,



I'm trying to run valgrind on my stack. Unfortunately it fails all time when
calling a function in the Judy lib (C libraries for creating and accessing
dynamic arrays: http://judy.sourceforge.net/)

I wonder if someone has success doing this (running valgrind on a code using
Judy array)?

I make a small test on which there is a call to the Judy lib. It works fine
but when I run it with valgrind ... It fails.!!



Here the test:



/***************************************************************************
*/

#include <unistd.h>
#include <stdio.h>
#include <string.h>
#include <Judy.h>



#define MAXLINE 65536           // max string (line) len



int  main()
{
    Pvoid_t   PJArray = (PWord_t)NULL;  // Judy array.
    PWord_t   PValue;                   // Judy array element.
    Word_t    Bytes;                    // size of JudySL array.
    char      Index[MAXLINE];           // string to check
    uint32_t  i=0;



    while ((fgets(Index, sizeof(Index), stdin) != "")&&(i++<5) )
    {
        JSLI(PValue, PJArray, Index);   // store string into array
        if (PValue == PJERR)            // if out of memory?
        {                               // so do something
            printf("ERROR \n"); exit(1);
        }
        ++(*PValue);                    // count instances of string
    }
    Index[0] = '\0';                    // start with smallest string.
    JSLF(PValue, PJArray, Index);       // get first string
    while (PValue != NULL)
    {
        while ((*PValue)--)             // print duplicates
            printf("%s", Index);
        JSLN(PValue, PJArray, Index);   // get next string
    }
    JSLFA(Bytes, PJArray);              // free array



    fprintf(stderr, "The JudySL array used %lu bytes of memory\n", Bytes);
    return (0);
}

 Many thanks in advance for your reply.

All the best,
