LIBRARYLinux Access Control Lists library (libacl, -lacl).
SYNOPSISIn sys/types.h In sys/acl.h Ft acl_t Fn acl_init int count
DESCRIPTIONThe Fn 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_free3 with the (void*)acl_t returned by Fn acl_init as an argument.
RETURN VALUEOn 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.
ERRORSIf any of the following conditions occur, the Fn acl_init function returns a value of (acl_t)NULL and sets errno to the corresponding value:
- Bq Er EINVAL
- The value of count is less than zero.
- Bq Er ENOMEM
- The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.
