Function Documentation

le_result_t le_path_Concat	(	const char *	separatorPtr,
		char *	pathPtr,
		size_t	pathSize,
			...
	)

Concatenates multiple path segments together.

Concatenates the path in the pathPtr buffer with all path segments and stores the result in the pathPtr. Ensures that where path segments are joined there is only one separator between them. Duplicate trailing separators in the resultant path are also dropped.

If there is not enough space in pathPtr for all segments, as many characters from the segments that will fit in the buffer will be copied and LE_OVERFLOW will be returned. Partial UTF-8 characters and partial separators will never be copied.

Warning

The (char*)NULL at the end of the list of path segments is mandatory. If this NULL is omitted the behaviour is undefined.

Returns

LE_OK if successful. LE_OVERFLOW if there was not enough buffer space in pathPtr for all segments.

Parameters

[in]	separatorPtr	Separator string.
[in,out]	pathPtr	Buffer containing the first segment and where the resultant path will be stored.
[in]	pathSize	Buffer size.

char* le_path_GetBasenamePtr	(	const char *	pathPtr,
		const char *	separatorPtr
	)

Gets a pointer to the basename (the last node in the path). This function gets the basename by returning a pointer to the character following the last separator.

Returns

Pointer to the character following the last separator.

Parameters

[in]	pathPtr	Path string.
[in]	separatorPtr	Separator string.

le_result_t le_path_GetDir	(	const char *	pathPtr,
		const char *	separatorPtr,
		char *	dirPtr,
		size_t	dirBuffSize
	)

Gets the directory, which is the entire path up to and including the last separator.

Returns

LE_OK if succesful. LE_OVERFLOW if the dirPtr buffer is too small.

Parameters

[in]	pathPtr	Path string.
[in]	separatorPtr	Separator string.
[out]	dirPtr	Buffer to store the directory string.
[in]	dirBuffSize	Size of the directory buffer in bytes.
