   acl_init    ( 3 )

инициализировать рабочее хранилище ACL (initialize ACL working storage)

Имя (Name)

acl_init — initialize ACL working storage

Библиотека (Library)

Linux Access Control Lists library (libacl, -lacl).

Синопсис (Synopsis)

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

acl_t acl_init(int count);


Описание (Description)

The acl_init() function allocates and initializes the working
     storage for an ACL of at least count ACL entries.  The ACL created
     initially contains no ACL entries.  A pointer to the working
     storage is returned.

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 returned by acl_init() as an argument.


Возвращаемое значение (Return value)

On success, this function returns a pointer to the working storage.
     On error, a value of (acl_t)NULL is returned, and errno is set
     appropriately.

Ошибки (Error)

If any of the following conditions occur, the acl_init() function
     returns a value of (acl_t)NULL and sets 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 constraints.
