dmmp_mpath_array_get(3)           Device Mapper Multipath API - libdmmp Manual

NAME
       dmmp_mpath_array_get - Query all existing multipath devices.

SYNOPSIS
       int dmmp_mpath_array_get (struct dmmp_context *ctx, struct dmmp_mpath
       ***dmmp_mps, uint32_t *dmmp_mp_count);

ARGUMENTS
       ctx         Pointer of 'struct dmmp_context'.  If this pointer is NULL,
                   your program will be terminated by assert.

       dmmp_mps    Output pointer array of 'struct dmmp_mpath'.  If this
                   pointer is NULL, your program will be terminated by assert.

       dmmp_mp_count
                   Output pointer of uint32_t. Hold the size of 'dmmp_mps'
                   pointer array.  If this pointer is NULL, your program will
                   be terminated by assert.

DESCRIPTION
       Query all existing multipath devices and store them into a pointer
       array.  The memory of 'dmmp_mps' should be freed via
       dmmp_mpath_array_free.

RETURN
       int. Valid error codes are:

       * DMMP_OK

       * DMMP_ERR_BUG

       * DMMP_ERR_NO_MEMORY

       * DMMP_ERR_NO_DAEMON

       * DMMP_ERR_INCONSISTENT_DATA

       Error number could be converted to string by dmmp_strerror.
