NAME

     acl_from_text — create an ACL from text

LIBRARY

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

SYNOPSIS

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

     acl_t
     acl_from_text(const char *buf_p);

DESCRIPTION

     The acl_from_text() function converts the text form of the ACL referred to by buf_p into the internal form
     of an ACL and returns a pointer to the working storage that contains the ACL. The acl_from_text() function
     accepts as input the long text form and short text form of an ACL as described in acl(5).

     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_from_text() as an
     argument.

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.

ERRORS

     If any of the following conditions occur, the acl_from_text() function returns a value of (acl_t)NULL and
     sets errno to the corresponding value:

     [EINVAL]           The argument buf_p cannot be translated into an ACL.

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

STANDARDS

     IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
