ACL_SET_QUALIFIER(3) BSD Library Functions Manual ACL_SET_QUALIFIER(3)
NAME
acl_set_qualifier - set the qualifier of an ACL entry
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
int
acl_set_qualifier(acl_entry_t entry_d, const void *qualifier_p);
DESCRIPTION
The acl_set_qualifier() function sets the qualifier of the ACL entry indicated by the
argument entry_d to the value referred to by the argument qualifier_p. If the value
of the tag type in the ACL entry referred to by entry_d is ACL_USER, then the value
referred to by qualifier_p shall be of type uid_t. If the value of the tag type in
the ACL entry referred to by entry_d is ACL_GROUP, then the value referred to by
qualifier_p shall be of type gid_t. If the value of the tag type in the ACL entry
referred to by entry_d is a tag type for which a qualifier is not supported,
acl_set_qualifier() returns an error.
Any ACL entry descriptors that refer to the entry referred to by entry_d continue to
refer to that entry. This function may cause memory to be allocated. The caller
should free any releasable memory, when the ACL is no longer required, by calling
acl_free() with a pointer to the ACL as argument.
RETURN VALUE
The acl_set_qualifier() 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_set_qualifier() function returns -1
and sets errno to the corresponding value:
[EINVAL] The argument entry_d is not a valid descriptor for an ACL entry.
The value of the tag type in the ACL entry referenced by the argu-
ment entry_d is neither ACL_USER nor ACL_GROUP.
The value pointed to by the argument qualifier_p is not valid.
[ENOMEM] The acl_set_qualifier() function is unable to allocate the memory
required for the ACL qualifier.
STANDARDS
IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
