ACL_CREATE_ENTRY(3) BSD 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 con- straints. SEE ALSO

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

ACL_CREATE_ENTRY(3) BSD Library Functions Manual ACL_CREATE_ENTRY(3) NAME
acl_create_entry -- create a new ACL entry LIBRARY
Linux Access Control Lists library (libacl, -lacl). SYNOPSIS
#include <sys/types.h> #include <sys/acl.h> int acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p); DESCRIPTION
The acl_create_entry() function creates a new ACL entry in the ACL pointed to by the contents of the pointer argument acl_p. On success, the function returns a descriptor for the new ACL entry via entry_p. This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with (void*)*acl_p as an argument. If the ACL working storage cannot be increased in the current location, then the working storage for the ACL pointed to by acl_p may be relocated and the previous working storage is released. A pointer to the new working storage is returned via acl_p. The components of the new ACL entry are initialized in the following ways: the ACL tag type component contains ACL_UNDEFINED_TAG, the quali- fier component contains ACL_UNDEFINED_ID, and the set of permissions has no permissions enabled. Any existing ACL entry descriptors that refer to entries in the ACL continue to refer to those entries. RETURN VALUE
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
If any of the following conditions occur, the acl_create_entry() function returns -1 and sets errno to the corresponding value: [EINVAL] The argument acl_p is not a valid pointer to an ACL. [ENOMEM] The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management con- straints. STANDARDS
