NAME acl_to_text - convert an ACL to text CONTENTS Library Synopsis Description Implementation Notes Return Values Errors See Also Standards History Authors Bugs LIBRARY .Lb libc SYNOPSIS .In sys/types.h .In sys/acl.h char * acl_to_text "acl_t acl" "ssize_t *len_p" DESCRIPTION The acl_to_text function translates the ACL pointed to by argument acl into a NULL terminated character string. If the pointer len_p is not NULL, then the function shall return the length of the string (not including the NULL terminator) in the location pointed to by len_p. The format of the text string returned by acl_to_text shall be the POSIX.1e long ACL form. This function allocates any memory necessary to contain the string and returns a pointer to the string. The caller should free any releasable memory, when the new string is no longer required, by calling acl_free(3) with the (void*)char as an argument. IMPLEMENTATION NOTES .Fx Ns ’s support for POSIX.1e interfaces and features is still under development at this time. RETURN VALUES Upon successful completion, the function shall return a pointer to the long text form of an ACL. Otherwise, a value of (char*)NULL shall be returned and errno shall be set to indicate the error. ERRORS If any of the following conditions occur, the acl_to_text function shall return a value of (acl_t)NULL and set errno to the corresponding value:

ERRORS If any of the following conditions occur, the acl_to_text function shall return a value of (acl_t)NULL and set errno to the corresponding value:
The ACL denoted by acl contains one or more improperly formed ACL entries, or for some other reason cannot be translated into a text form of an ACL.
