Using strings

• Read-only strings in input parameter
  

  C type	C comment	WLanguage type
  char*	read-only ANSI string	system integer (containing the address of an ANSI string: &string[ANSI])
  wchar*	read-only UNICODE string	system integer (containing the address of a Unicode string: &string unicode)

• Read/Write strings in input parameter
  

  C type	C comment	WLanguage type
  char*	read/write ANSI string	system integer (containing the address of a fixed Ansi string: &string[ANSI] on <Max length>)
  wchar*	read/write UNICODE string	system integer (containing the address of a fixed Unicode string: &string unicode on <Max Length>)

• Strings in return value
  

  C type	C comment	WLanguage type	WLanguage comment
  char*	ANSI string	system integer	use StringRetrieve(system integer, srASCIIZAddress)
  wchar*	UNICODE string	system integer	use StringRetrieve(system integer, srUNICODEAddress)

• Strings in output parameter
  

  C type	C comment	WLanguage type	WLanguage comment
  char**	ANSI string	system integer	address of another system integer containing the address to use with StringRetrieve(system integer, srASCIIZAddress)
  wchar**	UNICODE string	system integer	address of another system integer containing the address to use with StringRetrieve(system integer, srUNICODEAddress)

Using arrays of strings

• Array of strings in input parameter
  

  C type	C comment	WLanguage type	WLanguage comment
  char**	array of ANSI strings	system integer= &array of <N> integers	each array cell must be filled with the address of an Ansi string (&string[ANSI])
  wchar**	array of UNICODE strings	system integer = &array of <N> integers	each array cell must be filled with the address of a Unicode string (Unicode &string)

• Array of strings in return value
  

  C type	C comment	WLanguage type	WLanguage comment
  char**	array of ANSI strings + find out the size <N> elsewhere	system integer	you must use StringRetrieve(system integer, srASCIIZAddress) for each array cell
  wchar**	array of UNICODE strings + find out the size <N> elsewhere	system integer	you must use StringRetrieve(system integer, srUNICODEAddress) for each array cell

Strings and structures

• String directly in a structure
  

  C type	C comment	WLanguage type
  struct ... { char ...[N+1] };	read/write ANSI string	Struct is structure sString is string on N END AStruct is Struct StructAddress is a system integer=&AStruct
  struct ... { wchar ...[N+1] };	read/write UNICODE string	Struct is structure sString is UNICODE string on N END AStruct is Struct StructAddress is a system integer=&AStruct

• Read-only string in input in a structure
  

  C type	C comment	WLanguage type
  struct ... {char* ... };	read-only ANSI string	sString is [ANSI] string Struct is structure aString is int END AStruct is Struct AStruct:aString = &sString StructAddress is a system integer=&AStruct
  struct ... {wchar* ... };	read-only UNICODE string	sString is UNICODE string Struct is structure aString is int END AStruct is Struct AStruct:aString = &sString StructAddress is a system integer=&AStruct

• Read/Write string in input in a structure
  

  C type	C comment	WLanguage type
  struct ... {char* ... };	read/write ANSI string	sString is [ANSI] string on <Max length> Struct is structure aString is a system integer END AStruct is Struct AStruct:aString = &sString StructAddress is a system integer=&AStruct
  struct ... {wchar* ... };	read/write ANSI string	sString is UNICODE string on <Max Length> Struct is structure aString is a system integer END AStruct is Struct AStruct:aString = &sString StructAddress is a system integer=&AStruct

• String in output in a structure
  

  C type	C comment	WLanguage type	WLanguage comment
  struct ... {char* ... };	ANSI string	Struct is structure aString is a system integer END AStruct is Struct StructAddress is a system integer=&AStruct	+ use StringRetrieve (int, srASCIIZAddress)
  struct ... {wchar* ... };	UNICODE string	Struct is structure aString is a system integer END AStruct is Struct StructAddress is a system integer=&AStruct	+ use StringRetrieve (int, srUNICODEAddress)

Simple array in a structure

• Simple array directly in a structure
  

  C type	WLanguage type
  struct ... { type ... [N] };	Struct is structure t is fixed array of N <corresponding type> END AStruct is Struct StructAddress is a system integer=&AStruct

• Simple array in a structure
  

  C type	WLanguage type
  struct ... { type* ... };	t is array of N <corresponding type> Struct is structure aArray is int END AStruct is Struct AStruct:aArray = &t StructAddress is a system integer=&AStruct
