Detailed Description

Netatalk utility functions

Macro Definition Documentation

◆ GROUPSTR_BUFSIZE

#define GROUPSTR_BUFSIZE 1024

Function Documentation

◆ basename_safe()

const char * basename_safe ( const char * path )

Returns pointer to static buffer with basename of path

◆ become_root()

void become_root ( void )

◆ closeall()

void closeall ( int fd )

static

◆ daemonize()

int daemonize ( void )

Daemonize

Fork, exit parent, setsid(), chdir("/"), close all fds

returns -1 on failure, but you can't do much except exit in that case since we may already have forked

◆ fullpathname()

const char * fullpathname ( const char * name )

Request absolute path.

Returns: Absolute filesystem path to object

◆ getcwdpath()

const char * getcwdpath ( void )

get cwd in static buffer

Returns: pointer to path or pointer to error messages on error

◆ gmem()

int gmem	(	gid_t	gid,
		int	ngroups,
		gid_t *	groups )

◆ ochdir()

int ochdir	(	const char *	dir,
		int	options )

symlink safe chdir replacement

Only chdirs to dir if it doesn't contain symlinks or if symlink checking is disabled

Returns: 1 if a path element is a symlink, 0 otherwise, -1 on syserror

◆ ochmod()

int ochmod	(	char *	path,
		mode_t	mode,
		const struct stat *	st,
		int	options )

chmod() wrapper for symlink and ACL handling

Parameters

path	(r) path
mode	(r) requested mode
st	(r) stat() of path or NULL
options	(r) O_NOFOLLOW \| O_NETATALK_ACL

Options description: O_NOFOLLOW: don't chmod() symlinks, do nothing, return 0 O_NETATALK_ACL: call chmod_acl() instead of chmod() O_IGNORE: ignore chmod() request, directly return 0

◆ ochown()

int ochown	(	const char *	path,
		uid_t	owner,
		gid_t	group,
		int	options )

◆ ostat()

int ostat	(	const char *	path,
		struct stat *	buf,
		int	options )

◆ ostatat()

int ostatat	(	int dirfd	_U_,
		const char *	path,
		struct stat *	st,
		int	options )

◆ print_groups()

const char * print_groups	(	int	ngroups,
		gid_t *	groups )

◆ randombytes()

void randombytes	(	void *	buf,
		int	n )

Store n random bytes an buf

◆ realpath_safe()

char * realpath_safe ( const char * path )

◆ run_cmd()

int run_cmd	(	const char *	cmd,
		char **	cmd_argv )

Run command in a child and wait for it to finish

◆ set_groups()

int set_groups	(	AFPObj *	obj,
		struct passwd *	pwd )

◆ stripped_slashes_basename()

char * stripped_slashes_basename ( char * p )

Takes a buffer with a path, strips slashs, returns basename
