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>`__.
