gpfs_getacl() Subroutine Error status EINVAL The path name does not refer to a GPFS file or a regular file. ENOENT The file does not exist. ENOSPC The buffer is too small to return the entire ACL. The required buffer size is returned in the first four bytes of the buffer pointed to by aclP. ENOSYS The gpfs_getacl() subroutine is not supported under the current file system format.
