ACL_CREATE_ENTRY(3)     NetBSD Library Functions Manual    ACL_CREATE_ENTRY(3)


NAME

     acl_create_entry, acl_create_entry_np -- create a new ACL entry


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p);

     int
     acl_create_entry_np(acl_t *acl_p, acl_entry_t *entry_p, int index);


DESCRIPTION

     The acl_create_entry() function is a POSIX.1e call that creates a new ACL
     entry in the ACL pointed to by acl_p.  The acl_create_entry_np() function
     is a non-portable version that creates the ACL entry at position index.
     Positions are numbered starting from zero, i.e. calling
     acl_create_entry_np() with index argument equal to zero will prepend the
     entry to the ACL.


RETURN VALUES

     The acl_create_entry() function returns the value 0 if successful; other-
     wise the value -1 is returned and the global variable errno is set to
     indicate the error.


ERRORS

     The acl_create_entry() function fails if:

     [EINVAL]           Argument acl_p does not point to a pointer to a valid
                        ACL.  Argument index is out of bounds.

     [ENOMEM]           The ACL working storage requires more memory than is
                        allowed by the hardware or system-imposed memory man-
                        agement constraints.

STANDARDS
