''NAME : '' <b> gpfs_getacl() </b>
 
 
''FUNCTION : ''
 
 
Retrieves the ACL information for a file.
 
This function, together with gpfs_putacl, is intended for use by a backup program to save (gpfs_getacl) and restore (gpfs_putacl) the ACL information for a file. The flags parameter must be zero (reserved for future use). The '''aclP''' parameter must point to a buffer mapped by the ''gpfs_opaque_acl_t'' structure. The first four bytes of the buffer must contain its total size.
 
 
Note: The use of gpfs_fgetattrs/gpfs_fputattrs is preferred.

int gpfs_getacl(char *pathname, int flags, void *acl);

0 Successful

''ERROR :''
 
ENOSYS function not available
 
ENOSPC buffer too small to return the entire ACL.
 
Needed size is returned in the first four bytes of the buffer pointed to by aclP.
 
 
 
''NAME :'' <b> gpfs_putacl() </b>
 
 
''FUNCTION :''
 
 
Sets the ACL information for a file.
 
The buffer passed in should contain the ACL data that was obtained by a previous call to gpfs_getacl. The flags parameter must be zero (reserved for future use).
 
 
Note: The use of gpfs_fgetattrs/gpfs_fputattrs is preferred.
