PL_strdup
|
|
=========
|
|
|
|
Returns a pointer to a new memory node in the NSPR heap containing a
|
|
copy of a specified string.
|
|
|
|
|
|
Syntax
|
|
~~~~~~
|
|
|
|
.. code::
|
|
|
|
#include <plstr.h>
|
|
|
|
char *PL_strdup(const char *s);
|
|
|
|
|
|
Parameter
|
|
~~~~~~~~~
|
|
|
|
The function has a single parameter:
|
|
|
|
``s``
|
|
The string to copy, may be ``NULL``.
|
|
|
|
|
|
Returns
|
|
~~~~~~~
|
|
|
|
The function returns one of these values:
|
|
|
|
- If successful, a pointer to a copy of the specified string.
|
|
- If the memory allocation fails, ``NULL``.
|
|
|
|
|
|
Description
|
|
~~~~~~~~~~~
|
|
|
|
To accommodate the terminator, the size of the allocated memory is one
|
|
greater than the length of the string being copied. A ``NULL`` argument,
|
|
like a zero-length argument, results in a pointer to a one-byte block of
|
|
memory containing the null value.
|
|
|
|
Notes
|
|
~~~~~
|
|
|
|
The memory allocated by :ref:`PL_strdup` should be freed with
|
|
`PL_strfree </en/PL_strfree>`__.
