# object. Do not use this if the tuple may already be known to
|
|
# some other part of the code. The tuple will always grow or
|
|
# shrink at the end. Think of this as destroying the old tuple and
|
|
# creating a new one, only more efficiently. Returns 0 on
|
|
# success. Client code should never assume that the resulting
|
|
# value of *p will be the same as before calling this function. If
|
|
# the object referenced by *p is replaced, the original *p is
|
|
# destroyed. On failure, returns -1 and sets *p to NULL, and
|
|
# raises MemoryError or SystemError.
