#include <sys/acl.h>
int acl_clear_perm( acl_permset_t permset_d);
PARAMETERS
Specifies the permission set of the working storage internal representation of an ACL entry.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard.
The acl_clear_perm() function clears the permissions from the permission set in permset_d.
RETURN VALUES
Upon successful completion, the acl_clear_perm() function returns a value of 0 (zero). Otherwise a value of -1 is returned, and errno is

acl_init(3) Library Functions Manual acl_init(3)NAME
acl_init - Allocate and initialize ACL internal working storage
LIBRARY
Security Library (libpacl.a)
SYNOPSIS
#include <sys/acl.h>
acl_t acl_init( const size_t size);
PARAMETERS
Specifies the size of the working storage in bytes.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard.
The acl_init() function allocates and initializes working storage for an ACL of at least size bytes. A pointer to the working storage is
returned. When the area is first allocated, it contains a ACL that has no ACL entries.
RETURN VALUES
Upon successful completion, the acl_init() function returns a pointer to the working storage. Otherwise, a NULL pointer is returned and
errno is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_init() function returns a value of NULL and sets errno to the corresponding value: The
acl_t to be returned requires more memory than allowed by the hardware or system-imposed memory management constraints. The function is
not supported by the implementation.
