/* String object interface */
|
|
|
|
/*
|
|
Type PyStringObject represents a character string. An extra zero byte is
|
|
reserved at the end to ensure it is zero-terminated, but a size is
|
|
present so strings with null bytes in them can be represented. This
|
|
is an immutable object type.
|
|
|
|
There are functions to create new string objects, to test
|
|
an object for string-ness, and to get the
|
|
string value. The latter function returns a null pointer
|
|
if the object is not of the proper type.
|
|
There is a variant that takes an explicit size as well as a
|
|
variant that assumes a zero-terminated string. Note that none of the
|
|
functions should be applied to nil objects.
