strtok & strtok_r ERROR

[bali]

I'm developing a small function that split string using delimiter (,) but i can't use strtok (undeclared function error)

so i added (CONFIG_NEWLIB_LIBC=y) to prj.conf file 

and now i can run the code with no error but when I'm trying to use the function (strtok or strtok_r) i got an error undefined behaviour from the system

here's the function :

1) strtok_r

  char * token;

   while ((token= strtok_r(testBuffer, ',', &testBuffer)))
    printk("%s\n", token); 

2)strtok

char * token;

token= strtok(testBuffer, ',');
while (token != NULL)
{
token = strtok(NULL, ",");
}

any Suggestions?

Hi,

 

','

you want to delimit on the ascii ",", try setting this as char * s = ","; instead and see if it works better?

 

Kind regards,

Håkon

Thanks Hakon, your solution + i also forgot to initialise another NULL pointer 

so the final solution to make strtok_r works:

char cBuffer[255];

char * s = ",";
char *saveptr;
char * token;

for (token = strtok_r(cBuffer,s, &saveptr); token != NULL; token = strtok_r(NULL, ",", &saveptr)) {
      printk("%s\n", token);
}
