Release the pointer obtained from strtok

[Danut81]

Hi,

Having the following code:

char *Token = NULL;

Token = strtok("string","s");

How can I release the Token after I will no longer use the variable?

Hi,

what do you mean by 'release'?

If you want want to free allocated space I'm not sure it's necessary in this case.

Usually, when you allocate space to a pointer with malloc() or other functions, use free().

Hi Danut81.

There is no storage associated with your variable Token; it is a char * which the function strtok() sets to point to the next token found in your string, so there is nothing to free.

Don't "free" the Token. It's (just) a pointer into the "string" you want to process by strtok(). Similar to strchr() and others.

Bingo!

Thanks for the information.
