Member Function Documentation

create_iterator()

my_metadata::const_iterator my_metadata::create_iterator

(

)

Creates an iterator over the metadata.

Positions on the first value.

Returns

Reference to the iterator created.

get_value()

bool my_metadata::get_value	(	const char *	name,
		const char **	value
	)

Gets value for the name specified.

The value is unmodified if not found. Doesn't copy the result value, so it requires synchronization to prevent other threads to modify structure.

Parameters

	name	The name string of the metadata pair.
[out]	value	The value string of the metadata pair.

Returns

Status of performed operation

Return values

false	success
true	failure

release_iterator()

bool my_metadata::release_iterator ( const_iterator *  iter )

static

Frees an iterator over the metadata.

Iterator must be allocated through create_iterator();

Parameters

iter	Pointer to the iterator to release.

Returns

Status of performed operation

Return values

false	success
true	failure

set_value()

bool my_metadata::set_value	(	const char *	name,
		const char *	value
	)

Sets a value for the name specified.

Adds to the metadata list if absent. Copies the data into the structure, original values don't need to be around after this function is called.

Parameters

name	The name string of the metadata pair to be added.
value	The value string of the metadata pair.

Returns

Status of performed operation

Return values

false	success
true	failure
