Error: missing terminating character

[Alexander M.]

Hi,

I have a function with escape characters and ". Now when I try to build my module in the API out of line way, it says there is an terminating character missing. 

e.g.:

fprintf( sterr, " foo ", arga, argb, argc );

is going to be parsed (as seen in the module.c):

fprintf( stderr, " foo

",

              arga, argb, argc );

where the ", is clearly out of scope, an the rest of the function ins just not being recognised.

What am I missing?

Sorry, need to correct myself:

fprintf( sterr, " foo\n\n", arga, argb, argc );

so, I think the problem is the escaping \n. how can I realise this in the set_source function?

The '\n' is interpreted by Python as meaning "the end-of-line char".
To avoid that, use a r""" ... """:

ffibuilder.set_source("_foo", r"""

fprintf( sterr, " foo\n\n", arga, argb, argc );

""")


A bientôt,

Armin.
