Detailed Description

DBusString data structure for safer string handling.

Types and functions related to DBusString. DBusString is intended to be a string class that makes it hard to mess up security issues (and just in general harder to write buggy code). It should be used (or extended and then used) rather than the libc stuff in string.h. The string class is a bit inconvenient at spots because it handles out-of-memory failures and tries to be extra-robust.

A DBusString has a maximum length set at initialization time; this can be used to ensure that a buffer doesn't get too big. The _dbus_string_lengthen() method checks for overflow, and for max length being exceeded.

Try to avoid conversion to a plain C string, i.e. add methods on the string object instead, only convert to C string when passing things out to the public API. In particular, no sprintf, strcpy, strcat, any of that should be used. The GString feature of accepting negative numbers for "length of string" is also absent, because it could keep us from detecting bogus huge lengths. i.e. if we passed in some bogus huge length it would be taken to mean "current length of string" instead of "broken crack"

◆ _dbus_string_compact()

dbus_bool_t _dbus_string_compact	(	DBusString *	str,

	)

Compacts the string to avoid wasted memory.

Wasted memory is memory that is allocated but not actually required to store the current length of the string. The compact is only done if more than the given amount of memory is being wasted (otherwise the waste is ignored and the call does nothing).

Parameters

str	the string
max_waste	the maximum amount of waste to ignore

Returns: FALSE if the compact failed due to realloc failure

void _dbus_string_copy_to_buffer	(	const DBusString *	str,
		char *	buffer,

	)

Copies the contents of a DBusString into a different buffer.

It is a bug if avail_len is too short to hold the string contents. nul termination is not copied, just the supplied bytes.

Parameters

str	a string
buffer	a C buffer to copy data to
avail_len	maximum length of C buffer

◆ _dbus_string_get_data()

char * _dbus_string_get_data ( DBusString * str )

Gets the raw character buffer from the string.

The returned buffer will be nul-terminated, but note that strings may contain binary data so there may be extra nul characters prior to the termination. This function should be little-used, extend DBusString or add stuff to dbus-sysdeps.c instead. It's an error to use this function on a const string.

Parameters

str	the string

char * _dbus_string_get_data_len	(	DBusString *	str,

Gets a sub-portion of the raw character buffer from the string.

The "len" field is required simply for error checking, to be sure you don't try to use more string than exists. The nul termination of the returned buffer remains at the end of the entire string, not at start + len.

Parameters

str	the string
start	byte offset to return

◆ _dbus_string_init_const()

void _dbus_string_init_const	(	DBusString *	str,

Parameters

str	memory to use for the string
value	a string to be stored in str (not copied!!!)
