PR_GetProtoByNumber

Looks up a protocol entry based on protocol's number.

Syntax

#include <prnetdb.h>

PRStatus PR_GetProtoByNumber(
  PRInt32 protocolnumber,
  char* buffer,
  PRInt32 bufsize,
  PRProtoEnt* result);

The function has the following parameters:

protocolnumber: The number assigned to the protocol.
buffer: A pointer to a scratch buffer for the runtime to return result. This buffer is allocated by the caller.
bufsize: Number of bytes in the buffer parameter. The buffer must be at least PR_NETDB_BUF_SIZE bytes.
result: On input, a pointer to a PRNetAddr structure. 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.
