acl_init

ACL_INIT(3)						   BSD Library Functions Manual 					       ACL_INIT(3)

NAME

     acl_init -- initialize ACL working storage

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     acl_t
     acl_init(int count);

DESCRIPTION

     The acl_init() function allocates and initializes the working storage for an ACL of at least count ACL entries.  A pointer to the working
     storage is returned.  The working storage allocated to contain the ACL is freed by a call to acl_free(3).	When the area is first allocated,
     it shall contain an ACL that contains no ACL entries.

     This function may cause memory to be allocated.  The caller should free any releasable memory, when the new ACL is no longer required, by
     calling acl_free(3) with the (void*)acl_t as an argument.

RETURN VALUES

     Upon successful completion, this function shall return a pointer to the working storage.  Otherwise, a value of (acl_t)NULL shall be
     returned, and errno shall be set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_init() function shall return a value of (acl_t)NULL and set errno to the corresponding
     value:

     [EINVAL]		The value of count is less than zero.

     [ENOMEM]		The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.

SEE ALSO

     acl(3), acl_free(3), posix1e(3)

STANDARDS

     POSIX.1e is described in IEEE POSIX.1e draft 17.
