DPM_GETPROTOCOLS(3)

NAME

dpm_getprotocols - get the list of supported protocols

#include <sys/types.h>
#include "dpm_api.h"

int   dpm_getprotocols   (int   *nb_supported_protocols,  char  ***sup-
ported_protocols)

dpm_getprotocols gets the list of supported protocols.

nb_supported_protocols: will be set to the number of protocols in the array of supported protocols.
supported_protocols: will be set to the address of an array of pointers to the supported protocols. This array of pointers is allocated by the API and the client application is responsible for freeing the array when not needed anymore.

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

EFAULT nb_supported_protocols or supported_protocols is a NULL: pointer.
ENOMEM Memory could not be allocated for storing the array of: supported protocols.
SENOSHOST Host unknown.
SECOMERR Communication error.
