static int opd_add_ascii_map	(	struct opd_proc *	proc,
		char const *	line,
		char *const	image_name
	)			[static]

opd_add_ascii_map - parse an ASCII map string for a process

Parameters:

	proc	process to add map to
	line	0-terminated ASCII string
	image_name	the binary application name

Attempt to parse the string

and add the info to the process . Returns 1 on success, 0 otherwise.

The parsing is based on Linux 2.4 format, which looks like this :
