BuildTagDataSection()

std::vector<char> BuildTagDataSection	(	void *	section_data,
		int	size,
		int	start_offset
	)

Prepares a tag data section for saving.

This will build a list of all bytes for both the data section itself, as well as for any referenced data (such as blocks or tagrefs). It will also convert memory addresses to file offsets.

Parameters

section_data	- Address of the section data, would be either the tag data, or the block entry data.
size	- The size of the section data, would be either the tag's base size or the combined size of all block entries.
start_offset	- The start offset of the data. Used to convert memory addresses to file offsets.

Returns

A list of bytes representing the tag data section.

LoadSectionTagReferences()

void LoadSectionTagReferences	(	char *	address,
		int	size,
		std::string	tag_path
	)

Attempts to resolve any tag references within the given tag data section.

Parameters

address	- The data section address.
size	- The data section size.
tag_path	- The path of the tag. Used for debug messages.

LoadTagDataSection() [1/2]

void* LoadTagDataSection	(	int	offset,
		int	size,
		std::ifstream *	tag_file
	)

Loads a tag data section from a file.

This can be used to load both base tag data, as well as tag entry data.

Parameters

offset	- The offset to read from within the tag file.
size	- The size of the section data.
tag_file	- Pointer to the tag file to read from.

Returns

The address in memory of the newly loaded section.

LoadTagDataSection() [2/2]

void* LoadTagDataSection	(	int	offset,
		int	size,
		void *	tag_data_start_address
	)

Loads a tag data section from a file.

This can be used to load both base tag data, as well as tag entry data.

Parameters

offset	- The offset to read from within the tag file.
size	- The size of the section data.
tag_data_start_address	- Address pointing to the start of the tag data.

Returns

The address in memory of the newly loaded section.
