PR_GetHostByName
================
Looks up a host by name.
Syntax
------
.. code::
#include <prnetdb.h>
PRStatus PR_GetHostByName(
const char *hostname,
char *buf,
PRIntn bufsize,
PRHostEnt *hostentry);
Parameters
~~~~~~~~~~
The function has the following parameters:
``hostname``
The character string defining the host name of interest.
``buf``
A pointer to a buffer, allocated by the caller, that is filled in
with host data on output. All of the pointers in the ``hostentry``
structure point to data saved in this buffer. This buffer is
referenced by the runtime during a call to :ref:`PR_EnumerateHostEnt`.
``bufsize``
Number of bytes in the ``buf`` parameter. The buffer must be at least
:ref:`PR_NETDB_BUF_SIZE` bytes.
``hostentry``
This structure is allocated by the caller. On output, this structure
is filled in by the runtime if the function returns ``PR_SUCCESS``.
Returns
~~~~~~~
The function returns one of the following values:
- If successful, ``PR_SUCCESS``.
- If unsuccessful, ``PR_FAILURE``. You can retrieve the reason for the
failure by calling :ref:`PR_GetError`.
