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 mem‐ ory, 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)
