man acl_to_text (Fonctions bibliothèques) - acl_to_text
NAME
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
DESCRIPTION
The acl_to_text function translates the ACL pointed to by the argument acl into a NULL terminated character string. If the pointer len_p is not NULL , then the function returns the length of the string (not including the NULL terminator) in the location pointed to by len_p . The format of the text string returned by acl_to_text is the long text form defined in acl(5) . The ACL referred to by acl is not changed.
This function allocates any memory necessary to contain the string and returns a pointer to the string. The caller should free any releasable memory, when the new string is no longer required, by calling acl_free() with the (void*)char returned by acl_to_text as an argument.
RETURN VALUE
On success, this function returns a pointer to the long text form of the ACL. On error, a value of (char *)NULL is returned, and errno is set appropriately.
ERRORS
If any of the following conditions occur, the acl_to_text function returns a value of (char *)NULL and sets errno to the corresponding value:
- Bq EINVAL
- The argument acl is not a valid pointer to an ACL. The ACL referenced by acl contains one or more improperly formed ACL entries, or for some other reason cannot be translated into a text form of an ACL.
- Bq ENOMEM
- The character string to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.
