Syntax

#include <prnetdb.h>

PRStatus PR_GetHostByName(
  const char *hostname,
  char *buf,
  PRIntn bufsize,
  PRHostEnt *hostentry);

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 PR_EnumerateHostEnt.
bufsize: Number of bytes in the buf parameter. The buffer must be at least 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.

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 PR_GetError.
