ACL_FROM_TEXT(3) BSD Library Functions Manual ACL_FROM_TEXT(3) NAME
acl_to_text -- convert an ACL to text LIBRARY
Linux Access Control Lists library (libacl, -lacl). SYNOPSIS
#include <sys/types.h> #include <sys/acl.h> char * acl_to_text(acl_t acl, ssize_t *len_p); 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(3) 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: [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 trans- lated into a text form of an ACL. [ENOMEM] The character string to be returned requires more memory than is allowed by the hardware or system-imposed memory manage- ment constraints. STANDARDS

ACL_TO_ANY_TEXT(3) BSD Library Functions Manual ACL_TO_ANY_TEXT(3) NAME
acl_to_any_text -- convert an ACL to text LIBRARY
Linux Access Control Lists library (libacl, -lacl). SYNOPSIS
#include <sys/types.h> #include <acl/libacl.h> char * acl_to_any_text(acl_t acl, const char *prefix, char separator, int options); DESCRIPTION
The acl_to_any_text() function translates the ACL pointed to by the argument acl into a NULL terminated character string. This character string is composed of the ACL entries contained in acl, in the entry text format described on acl(5). Entries are separated from each other by the separator character. If the argument prefix is not (const char *)NULL, each entry is prefixed by this character string. If the argument options is 0, ACL entries are converted using the entry tag type keywords user, group, mask, and other. User IDs and group IDs of ACL entries that contain such qualifiers are converted to their corresponding names; if an identifier has no corresponding name, a decimal number string is produced. The ACL text representation contains no additional comments. A bitwise combinations of the following options can be used to modify the result: TEXT_ABBREVIATE Instead of the full tag type keywords, single letter abbreviations are used. The abbreviation for user is u, the abbreviation for group is g, the abbreviation for mask is m, and the abbreviation for other is o. TEXT_NUMERIC_IDS User IDs and group IDs are included as decimal numbers instead of names. TEXT_SOME_EFFECTIVE A comment containing the effective permissions of the ACL entry is included after ACL entries that contain permissions which are ineffective because they are masked by an ACL_MASK entry. The ACL entry and the comment are separated by a tab character. TEXT_ALL_EFFECTIVE A comment containing the effective permissions of the ACL entry is included after all ACL entries that are affected by an ACL_MASK entry. The comment is included even if the permissions contained in the ACL entry equal the effective permissions. The ACL entry and the comment are separated by a tab character. TEXT_SMART_INDENT This option is used in combination with the TEXT_SOME_EFFECTIVE or TEXT_ALL_EFFECTIVE option. The number of tab characters inserted between the ACL entry and the comment is increased so that the comment is aligned to the fourth tab stop position. A tab width of 8 characters is assumed. 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_any_text() as an argument. RETURN VALUE
On success, this function returns a pointer to the text representation 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_any_text() function returns a value of (char *)NULL and sets errno to the corresponding value: [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 trans- lated into the text form of an ACL. [ENOMEM] The character string to be returned requires more memory than is allowed by the hardware or system-imposed memory manage- ment constraints. STANDARDS
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", aban- doned). SEE ALSO
