The acl_from_text function converts the text form of an ACL referred to by buf_p into the internal working structure for ACLs, appropriate for applying to files or manipulating.
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 as an argument.
.Fx Ns s support for POSIX.1e interfaces and features is still under development at this time.
Upon successful completion, the function shall return a pointer to the internal representation of the ACL in working storage. Otherwise, a value of (acl_t)NULL shall be returned, and errno shall be set to indicate the error.
If any of the following conditions occur, the acl_from_text function shall return a value of (acl_t)NULL and set errno to the corresponding value:
