/*  SYNOPSIS */
	AROS_LHA(STRPTR, name, D1),

/*  LOCATION */
	struct DosLibrary *, DOSBase, 25, Dos)

/*  FUNCTION
	Loads an executable file into memory. Each hunk of the loadfile
	is loaded into his own memory section and a handle on all of them
	is returned. The segments can be freed with UnLoadSeg().

    INPUTS
	name - NUL terminated name of the file.

    RESULT
	Handle to the loaded executable or 0 if the load failed.
	IoErr() gives additional information in that case.
