ACL_CREATE_ENTRY(3)

ACL_CREATE_ENTRY(3) | 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; otherwise 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 management constraints.

# STANDARDS

POSIX.1e is described in IEEE POSIX.1e draft 17.

# HISTORY

POSIX.1e support was introduced in FreeBSD 4.0. The `acl_create_entry`() function was added in FreeBSD 5.0.

# AUTHORS

The `acl_create_entry`() function was written by Chris D. Faulhaber <jedgar@fxp.org>.
