That is very odd. Have you contacted to determine is there is a problem?

Good idea, I've sent a mail.

! When @code{strchr} returns a null pointer, it does not let you know
! the position of the terminating null character it has found.

What are you trying to say here? Could you please expand this sentence.

Sorry, my English is not very good. I'll try to explain more:

strchr ("my very long string containing no dashes...", '-') reads the whole string until its terminating NUL character, then returns the NULL pointer once it has found the said NUL character.

I have a program that does not know in advance the length of the string, and it is annoying that strchr does not provide that information even though it has found it. My program has to perform a strlen() which means a second full-length read of the string.

strchrnul, if I understand correctly, has the functionality of strchr while providing that information, since it provides a pointer to the ending NUL character. The string length can be computed with the difference between pointers.
