read_file(TCL)

read_file -- read file and return contents as string

Syntax

read_file [-nonewline] fileName" "read_file fileName numBytes

Description

This procedure reads the file fileName and returns the contents as a string. If -nonewline is specified, then the last character of the file is discarded if it is a newline. The second form specifies exactly how many bytes will be read and returned, unless there are fewer than numBytes bytes left in the file; in this case, all the remaining bytes are returned.
