ACL_FROM_TEXT(3)	 BSD Library Functions Manual	      ACL_FROM_TEXT(3)

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 argu‐
     ment.

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 appropri‐
     ately.

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 man‐
			agement constraints.

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