tokenize string to array of strings c

[Scotty33]

Hi,
I've gotten pretty good at C but can't seem to logically or actually figure this out....


I'm taking a string, it can be any string, and tokenizing it. This is the part of the code that matters. How do I save each token to a new string? There is an unknown amount of tokens.


I know I could define X amount of strings but I want to do this dynamically.

tok = strtok(getenv("PATH"), ":");
	printf("Tokens: \n");
	
	while (tok != NULL){
		printf("%s\n", tok);
		tok = strtok(NULL, ":");
}

Thanks!

First look up strtok() in your compiler's library documentation (don't have it? ... get it!)

strtok() returns a pointer to the isolated string.
All you have to do is save the pointers in an array.

It also alters the string, so you probably don't want to use the getenv() command inside your first strtok call... it would be far better to copy it to a separate string than trying to operate on an environment variable directly. (Ask how badly you want to screw up your system...)
