These output functions can be used as substitution of the standard text
|
|
output functions to get the value of text fields printed in the format
|
|
used for C strings. This allows the output of queries or the exported
|
|
files to be processed more easily using standard unix filter programs
|
|
like perl or awk.
|
|
|
|
If you use the standard functions instead you could find a single tuple
|
|
splitted into many lines and the tabs embedded in the values could be
|
|
confused with those used as field delimters.
|
|
|
|
My function translates all non-printing characters into corresponding
|
|
esacape sequences as defined by the C syntax. All you need to reconstruct
|
|
the exact value in your application is a corresponding unescape function
|
|
like the string_input defined in the source code.
