Use of _ in string causes sdssplitlen() to return no tokens about sds HOT 1 OPEN

I am not sure if this helps or not, but seems to work ok.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "sds.h"
#include "sdsalloc.h"

int main( int argc, char *argv[] )
{

sds *tokens;
int count, j;
FILE *fp;
char path[10350];

/* Open the command for reading. */
fp = popen("/usr/bin/find /home/user/Desktop/|tr '/' '_'", "r");
if (fp == NULL) {
printf("Failed to run command\n" );
exit(1);
}

/* Read the output a line at a time - output it. */
while (fgets(path, sizeof(path)-1, fp) != NULL) {
{
sds y = sdsnew(path);
printf("%s",y);
sds line = sdsnew(y);
tokens = sdssplitlen(line,sdslen(line),"home_user",9,&count);
for (j = 0; j < count; j++)
printf("%s\n", tokens[j]);
sdsfreesplitres(tokens,count);
}}

/* close */
pclose(fp);
return 0;
}

from sds.
