Is strtok in C89?

Question

Is the strtok function in standard C89?

You could ask such a question here for every single function used in any C program, or you could look it up. — Jim Balter, Mar 05 '11 at 08:33
Where can you check if a function belongs to a given standard in an easy way? — M.E., Jan 28 '21 at 13:23

the man page says:

CONFORMING TO
       strtok()
              SVr4, POSIX.1-2001, 4.3BSD, C89, C99.

       strtok_r()
              POSIX.1-2001.

So I would say yes.

According to the C89 draft I have (the actual standard costs money), the appropriate section is:

4.11 STRING HANDLING <string.h>

4.11.5.8 The strtok function

There are lists enumerating functions and other identifiers by standard and header. See e.g. http://www.schweikhardt.net/identifiers.html
