explain_acl_set_file_or_die - set an ACL by filename and report errors
#include <libexplain/acl_set_file.h>
void explain_acl_set_file_or_die(const char *pathname, acl_type_t type, acl_t
acl);
int explain_acl_set_file_on_error(const char *pathname, acl_type_t type, acl_t
acl);
The
explain_acl_set_file_or_die function is used to call the
acl_set_file(3) system call. On failure an explanation will be printed
to
stderr, obtained from the
explain_acl_set_file(3) function,
and then the process terminates by calling exit(EXIT_FAILURE).
The
explain_acl_set_file_on_error function is used to call the
acl_set_file(3) system call. On failure an explanation will be printed
to
stderr, obtained from the
explain_acl_set_file(3) function,
but still returns to the caller.
- pathname
- The pathname, exactly as to be passed to the acl_set_file(3) system
call.
- type
- The type, exactly as to be passed to the acl_set_file(3) system
call.
- acl
- The acl, exactly as to be passed to the acl_set_file(3) system
call.
The
explain_acl_set_file_or_die function only returns on success, see
acl_set_file(3) for more information. On failure, prints an explanation
and exits, it does not return.
The
explain_acl_set_file_on_error function always returns the value
return by the wrapped
acl_set_file(3) system call.
The
explain_acl_set_file_or_die function is intended to be used in a
fashion similar to the following example:
explain_acl_set_file_or_die(pathname, type, acl);
- acl_set_file(3)
- set an ACL by filename
- explain_acl_set_file(3)
- explain acl_set_file(3) errors
- exit(2)
- terminate the calling process
