    NAME

    dat_registry_list_providers - obtain a list of available pProviders from the Static Registry
     
    

    SYNOPSIS

    typedef struct dat_provider_info {
       char ia_name[DAT_NAME_MAX_LENGTH];
       DAT_UINT32      dapl_version_major;
       DAT_UINT32      dapl_version_minor;
       DAT_BOOLEAN     is_thread_safe;
       } DAT_PROVIDER_INFO;
    
    cc [ flag... ] file... -ldat [ library... ] 
    #include <dat/udat.h>
    
    DAT_RETURN
       dat_registry_list_providers (
       IN    DAT_COUNT          max_to_return,
       OUT   DAT_COUNT          *number_entries,
       OUT   DAT_PROVIDER_INFO  *(dat_provider_list[])
       )
    

     

    PARAMETERS

    max_to_return

    Maximum number of entries that can be returned to the Consumer in the dat_provider_list.

    number_entries

    The actual number of entries returned to the Consumer in the dat_provider_list if successful or the number of Providers available.

    dat_provider_list

    Points to an array of DAT_PROVIDER_INFO pointers supplied by the Consumer. Each Provider's information will be copied to the destination specified.

     

    DESCRIPTION

    The dat_registry_list_providers() function allows the Consumer to obtain a list of available Providers from the Static Registry. The information provided is the Interface Adapter name, the uDAPL/kDAPL API version supported, and whether the provided version is thread-safe. The Consumer can examine the attributes to determine which (if any) Interface Adapters it wants to open. This operation has no effect on the Registry itself.

    The Registry can open an IA using a Provider whose dapl_version_minor is larger than the one the Consumer requests if no Provider entry matches exactly. Therefore, Consumers should expect that an IA can be opened successfully as long as at least one Provider entry returned by dat_registry_list_providers() matches the ia_name, dapl_version_major, and is_thread_safe fields exactly, and has a dapl_version_minor that is equal to or greater than the version requested.

    If the operation is successful, the returned value is DAT_SUCCESS and number_entries indicates the number of entries filled by the registry in dat_provider_list.

    If the operation is not successful, then number_entries returns the number of entries in the registry. Consumers can use this return to allocate dat_provider_list large enough for the registry entries. This number is just a snapshot at the time of the call and may be changed by the time of the next call. If the operation is not successful, then the content of dat_provider_list is not defined.

    If dat_provider_list is too small, including pointing to NULL for the registry entries, then the operation fails with the return DAT_INVALID_PARAMETER.  

    RETURN VALUES

    DAT_SUCCESS

    The operation was successful.

    DAT_INVALID_PARAMETER

    Invalid parameter. For example, dat_provider_list is too small or NULL.

    DAT_INTERNAL_ERROR

    Internal error. The DAT static registry is missing.

     

    USAGE

    DAT_NAME_MAX_LENGTH includes the null character for string termination.
