NAME

read_buffer() - read from a file and return a buffer, or return part of
a buffer as a string

SYNOPSIS

string | buffer read_buffer( string | buffer src,
int start,  int len );

DESCRIPTION

If 'src' is a string (filename), then the filename will be read, start‐
ing  at  byte # 'start', for 'len' bytes, and returned as a buffer.  If
neither argument is given, the entire file is read.

If 'src' is a buffer, then characters are read from the  buffer  begin‐
ning  at  byte  #  'start' in the buffer, and for 'len' # of bytes, and
returned as a string.

Note that the maximum number of bytes you can read from a file and into
a buffer is controlled via the 'maximum byte transfer' parameter in the
runtime config file.
