unsigned int File__byte_read ( File file )

Read a byte from *file*.

Parameters:

file	to read from.

Returns:: byte read from *file*.

File__byte_read*() will read a byte from *file* and return it.

Definition at line 17 of file File.cpp.

void File__byte_write	(	File	file,
		unsigned int	byte
	)

Write *byte* ot *file*.

Parameters:

file	to read from.
byte	to write out.

File__byte_write*() will write *byte* to *file*.

Definition at line 29 of file File.cpp.

int File__character_read ( File in_file )

Return the next character read from *in_file*.

Parameters:

in_file to read from.

Returns:: character read from *in_file*.

File__character_read*() will read in and return the next character from *in_file*. (*char*)(-1) is returned when an end of file condition is encountered on *in_file*.

Definition at line 41 of file File.cpp.

void File__close ( File file )

Closes *file*.

Parameters:

file to close.

File__close*() will close *file*.

Definition at line 50 of file File.cpp.

double File__double_attribute_read	(	File	in_file,
		String_Const	attribute_name
	)

Reads in an XML attribute with a floating point value.

Parameters:

in_file	is the input file to read from.
attribute_name	is the attribute name.

Returns:: the floating point value.

File__double_attribute_read*() will read in a pattern that matches ' ATTRIBUTE_NAME="VALUE"', where ATTRIBUTE_NAME matches *attribute_name* and VALUE is an optionally signed floating point number. This is used for parsing "XML" file input. "XML" is in quotes is because this is really not a very robust XML parser. An assertion failure occurs if the input does not parse properly.

Definition at line 66 of file File.cpp.

float File__float_attribute_read	(	File	in_file,
		String_Const	attribute_name
	)

Reads in an XML attribute with a floating point value.

Parameters:

in_file	is the input file to read from.
attribute_name	is the attribute name.

Returns:: the floating point value.

File__float_attribute_read*() will read in a pattern that matches ' ATTRIBUTE_NAME="VALUE"', where ATTRIBUTE_NAME matches *attribute_name* and VALUE is an optionally signed floating point number. This is used for parsing "XML" file input. "XML" is in quotes is because this is really not a very robust XML parser. An assertion failure occurs if the input does not parse properly.

Definition at line 128 of file File.cpp.

void File__flush ( File file )

Flushes file content out of internal buffers.

Parameters:

file to flush.

File__flush*() will flush out the internal buffers of *out_file*.

Definition at line 166 of file File.cpp.

void File__format	(	File	file,
		String_Const	format,
			...
	)

will write *format* out to *file* with all patterns that start with "%" replaced by formatted versions of its arguments.

Parameters:

file	to output to.
format	is the formatting string.

File__format*() will write *format* out to *file* with all patterns that start with "%" replaced by formatted versions of its arguments.

Definition at line 107 of file File.cpp.

int File__integer_attribute_read	(	File	in_file,
		String_Const	attribute_name
	)

Reads in an XML attribute with a integer value.

Parameters:

in_file	is the input file to read from.
attribute_name	is the attribute name.

Returns:: the floating point value.

File__integer_attribute_read*() will read in a pattern that matches ' ATTRIBUTE_NAME="VALUE"', where ATTRIBUTE_NAME matches *attribute_name* and VALUE is an optionally signed integer number. This is used for parsing "XML" file input. "XML" is in quotes is because this is really not a very robust XML parser. An assertion failure occurs if the input does not parse properly.

Definition at line 183 of file File.cpp.

unsigned int File__little_endian_short_read ( File file )

Read a little endian short (16-bits) from *file*.

Parameters:

file	to read from.

Returns:: 16-bit value from *file*.

File__little_endian_short_read*() will read a 16-bit unsigned integer from *file* and return it.

Definition at line 215 of file File.cpp.

void File__little_endian_short_write	(	File	file,
		unsigned int	xshort
	)

Write 16-bit *xshort* to *file* in little endian format.

Parameters:

file	to write.
xshort	to write.

File__little_endian_short_write*() will write write *xshort* to *file* as a little endian 16-bit unsigned integer.

Definition at line 231 of file File.cpp.

File File__open	(	String_Const	file_name,
		String_Const	flags
	)

will open *file_name* using *flags* to specify read/write options.

Parameters:

file_name	is the file name to open.
flags	specify the read/write options.

File__open*() will open *file_name* using *flags* to read/write options. An open *File* object is returned or (*File)0 if the open failed.

Definition at line 243 of file File.cpp.

void File__string_match	(	File	in_file,
		String_Const	pattern
	)

Exactly matches *pattern* read from *in_file*.

Parameters:

in_file	to read from.
pattern	to matach.

File__string_match*() will read characters from *in_file* that must exactly match *pattern*. An assertion failure occurs if *pattern* does not match exactly.

Definition at line 255 of file File.cpp.

void File__tag_match	(	File	in_file,
		String_Const	tag_name
	)

Matchs and "XML" start tag.

Parameters:

in_file	is the file to read from.
tag_name	is the name of the tat to match.

File__tag_match*() parse "WHITESPACE<TAG" where WHTITESPACE is zero or more spaces and TAG matches *tag_name*. An assertion failure occurs the pattern does not parse properly. This is not a very robust XML parser.
