Split string with delimiters in C

What’s the best way to split a “,” separated list into an array in C. I know how many things are in the list.

char list = "one,two,three,four";
int ENTServerAmount = 8;
char **ENTServer;
ENTServer = malloc(sizeof(char *) * ENTServerAmount);
*** Code that splits "list" into "ENTServer" ***

Also I’m not very good at allocating so let me know if my allocation statement is wrong.

Answer 1

strtok() is probably the function you are looking for.

char list[] = "one,two,three,four";
int ENTServerAmount = 8;
char **ENTServer;

char *tmp = strtok (str, ",");

int index = 0;
while (pch != NULL)
{
   ENTSever[index++] = tmp;
   tmp = strtok (NULL, ",");
}
