Detailed Description

This class contains a collection of static functions for reading and writing simple types, in network byte order (MSB first).

It also contains functions to read and write strings. It also contains function templates to read and write STL deques, lists, vectors, maps, multimaps, sets, multisets, unordered_maps, unordered_multimaps, unordered_sets, unordered_multisets, tuples and variants. We use our member functions to handle reading and writing simple types in the containers, and function templates to handle reading and writing other class types. For a user-defined class, the class must implement the FileReadable and FileWritable interfaces, since our function templates simply call out to them. Since templates are static polymorphism, you don't need to inherit from FileReadable and FileWritable, but you must implement the interfaces.

		uint16_t	val )

static

Writes val to f, in network byte order (MSB first).

Returns the number of bytes written (2) on success.

◆ Write() [24/26]

static size_t Dwm::FileIO::Write	(	FILE *	f,
		uint32_t	val )

static

Writes val to f, in network byte order (MSB first).

Returns the number of bytes written (4) on success.

◆ Write() [25/26]

static size_t Dwm::FileIO::Write	(	FILE *	f,
		uint8_t	c )

static

Writes c to f.

Returns the number of bytes written (1) on success.

◆ Write() [26/26]

static size_t Dwm::FileIO::Write	(	FILE *	fp,
		const std::monostate &	sm )

inlinestatic

Just a dummy helper function for std::variant instances that hold a std::monostate.

This should only be called from our Write() for std::variant (via std::visit()), and does nothing. Returns 1.

◆ WriteV()

template<typename... Args>

static size_t Dwm::FileIO::WriteV	(	FILE *	f,
		const Args &...	args )

inlinestatic

Writes multiple objects to a FILE.

Returns 1 on success, 0 on failure.
