The Erec, Lrec Srec layouts contain the following:
A format specifier for parsing ASCII responses
●
A format specifier for parsing binary responses
●
In addition to these the Erec Layout contains:
A format specifier for producing the front-panel displays
●
Values are read in using either the ASCII or binary format specifiers and
converted to uniform internal representations (32-bit floats or 32-bit
integers). These values are converted into text for display on the screen
using the format specifier for the front-panel display. Normally, the
specifier used to parse a particular datum from the input stream will be
strongly related to the specifier used to display it (such as, all of the floating
point inputs will be displayed with an 'f' output specifier, and all of the
integer inputs will be displayed with a 'd' specifier).
The first line of the Layout response is the scanf-like parameter list for
parsing the fields from an ASCII ERec response. Parameters are separated
by spaces and the line is terminated by a \n (the normal line separator
character). Valid fields are:
%s - parse a string
%d - parse a decimal number
%ld - parse a long (32-bit) decimal number
%f - parse a floating point number
%x - parse a hexadecimal number
%lx - parse a long (32-bit) hex number
%* - ignore the field
Note Signed versus unsigned for the integer values does not matter; it is
handled automatically. ▲
