Mkfile()

void Mkfile	(	const char *	filename,
		const char *	ext )

Create a new empty file entry in the FAT16 root directory.

Creates a new empty file in the FAT16 root directory.

This function searches for a free root directory entry and a free cluster, then creates a new directory entry for the specified filename and extension. It initializes the directory entry with default attributes and zero file size.

Parameters

filename	The 8-character filename (without extension).
ext	The 3-character file extension.

Note

The function assumes FAT16 filesystem data is accessible through the global fat16 structure.

Warning

If no free directory entry or cluster is available, the function prints an error message and returns without creating the file.
