Subject: [Outreachy] Return value before or after free()?
Date: Mon, 6 Jan 2020 22:15:53 +0100 [thread overview]
Message-ID: <CAN7CjDDBA0ZoCG9aaQf5rg3gxqny=EjR6v6jE1mnxvUJQSF_0Q@mail.gmail.com> (raw)
Dear all,
in run-command.c file `exists_in_PATH()` function does this:
static int exists_in_PATH(const char *file)
{
char *r = locate_in_PATH(file);
free(r);
return r != NULL;
}
I wonder if it is correct to do return r != NULL; after free(r);
Could be this version more readable? :
static int exists_in_PATH(const char *file)
{
char *r = locate_in_PATH(file);
int res = (r != NULL);
free(r);
return res;
}
Could you please give me your feedback?
Thank you!
Best,
Miriam.
