acl_create_entry_np3
Create a new acl entry
Part of acl_create_entry(3).
Usage
#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);
Library
Standard C Library (libc, -lc)
Overview
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.
