gpfs_getacl() function, in the docs you pass acl, and the notes say “Pointer
to a buffer mapped by the structure gpfs_opaque_acl_t or gpfs_acl_t, depending
on the value of flags. The first four bytes of the buffer must contain
its total size.”. Reading the docs for gpfs_opaque_acl_t, this is a struct
of which the first element is an int. Is this the same 4 bytes referred
to as above containing the size, and is this the size of the struct, of
of the acl_var_data entry?</span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri"> </span></p><p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;font-family:Calibri">It
