Function Documentation

proc_copy_out()

size_t proc_copy_out	(	char *	buf,
		size_t	size,
		uint64_t	offset,
		const char *	src,
		size_t	len )

Copies a slice of the source string into the destination buffer.

The slice starts at offset. At most size - 1 bytes are copied and the result is always NUL-terminated. If offset is past the end of the source string, the destination buffer is set to an empty string.

Parameters

buf	destination buffer
size	size of the destination buffer in bytes
offset	byte offset into the source string
src	source string
len	length of the source string in bytes

Returns

the number of bytes copied

proc_fs_create_readonly_file()

inode_t proc_fs_create_readonly_file	(	const char *	name,
		proc_read_t *	read_fn )

Todo

We probably want a specific driver for read-only pseudo-files.

proc_fs_init()

int proc_fs_init

(

)

Initializes the "proc" file system.

The "proc" file system exposes kernel information using files.

Returns

0 on success
