ACL_SET_QUALIFIER(3)					   BSD Library Functions Manual 				      ACL_SET_QUALIFIER(3)

NAME
acl_set_qualifier -- set ACL tag qualifier LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/types.h> #include <sys/acl.h> int acl_set_qualifier(acl_entry_t entry_d, const void *tag_qualifier_p); DESCRIPTION
The acl_set_qualifier() function is a POSIX.1e call that sets the qualifier of the tag for the ACL entry entry_d to the value referred to by tag_qualifier_p. RETURN VALUES
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
The acl_set_qualifier() function fails if: [EINVAL] Argument entry_d is not a valid descriptor for an ACL entry. The tag type of the ACL entry entry_d is not ACL_USER or ACL_GROUP. The value pointed to by tag_qualifier_p is not valid. [ENOMEM] The value to be returned requires more memory than is allowed by the hardware or system-imposed memory management con- straints. SEE ALSO
acl(3), acl_get_qualifier(3), posix1e(3) STANDARDS
POSIX.1e is described in IEEE POSIX.1e draft 17. HISTORY
POSIX.1e support was introduced in FreeBSD 4.0. The acl_get_qualifier() function was added in FreeBSD 5.0. AUTHORS
The acl_get_qualifier() function was written by Chris D. Faulhaber <jedgar@fxp.org>. BSD

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 argu- ment 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 argument 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
