acl_init(3)acl_init(3)NAMEacl_init - Allocate and initialize ACL internal working storage
SYNOPSIS
#include <sys/acl.h>
acl_t acl_init(
const size_t size );
LIBRARY
Security Library (libpacl.a)
PARAMETERS
Specifies the size of the working storage in bytes.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 stan‐
dard.
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.
