man acl_copy_int (Fonctions bibliothèques) - acl_copy_int
NAME
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
DESCRIPTION
The acl_copy_int function copies an exportable, contiguous, persistent form of an ACL, pointed to by buf_p , to the internal representation.
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() with the (void*)acl_t returned by acl_copy_int as an argument.
RETURN VALUE
Upon success, the acl_copy_int function returns a pointer that references the ACL in working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.
ERRORS
If any of the following conditions occur, the acl_copy_int function returns a value of (acl_t)NULL and sets errno to the corresponding value:
- Bq EINVAL
- The buffer pointed to by the argument buf_p does not contain a valid external form ACL.
- Bq ENOMEM
- The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
STANDARDS
IEEE Std 1003.1e draft 17 (POSIX.1e, abandoned)
