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.

acl_set_qualifier - Sets the tag qualifier (UID or GID) on an ACL entry
LIBRARY
Security Library (libpacl.a)
SYNOPSIS
#include <sys/acl.h>
int acl_set_qualifier( acl_entry_t entry_d; void *tag_qualifier_p);
PARAMETERS
Designates the working storage internal representation ACL entry to set the tag qualifier in. Designates the uid or gid to set the tag
qualifier to.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard.
Given an ACL entry, the acl_set_qualifier() function sets the id in the ACL entry. If the tag type of the given ACL entry is ACL_USER then
tag_qualifier_p is evaluated as a pointer of type *uid_t. If the tag type of the given ACL entry is ACL_GROUP then tag_qualifier_p is
evaluated as a pointer of type *gid_t. Any other ACL tag type results in an error.
RETURN VALUES
Upon successful completion, the acl_set_qualifier() function returns a value of 0 (zero). Otherwise, a value of -1 is returned and errno
is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_set_qualifier() function sets errno to the corresponding value:
Argument entry_d does not refer to a valid ACL entry.
The value of the tag type in ACL entry referred to by entry_d is ACL_USER_OBJ, ACL_GROUP_OBJ, or ACL_OTHER_OBJ.
The value of the entry in tag_qualifier_p is not valid. There is not enough memory available to allocate the ACL uid/gid storage.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
