ap_ getword — extract one word from a list of words
char *ap_ getword(pool *p, const char **line, char stop) char *ap_ getword_nc(pool *p, char **line, char stop)
Looks for the first occurrence of stop in
*line and copies everything before it to a new
buffer, which it returns. If *line contains no
stops, the whole of *line is
copied. *line is updated to point after the
occurrence of stop, skipping multiple instances of
stop if present. ap_ getword_nc(
) is a version of ap_ getword() that
takes a nonconstant pointer. This is because some C compilers
complain if a char ** is passed to a function
expecting a const char **.
