[PATCH v2 0/4] tools: iio: Send error messages to stderr

[Cristina Opriceana <cristina.opriceana@gmail.com>]

This patchset indends to make some cleanup and send printf
error messages to stderr. The changes were performed with coccinelle for
failure messages and manual for other cases. The following script
was used:

@r@
expression e1, e2, stdout;
@@
(printf(e1);
|
printf(e1, e2);
|
fprintf(stdout, e1);
|
fprintf(stdout, e1, e2);
)
@script: python get_string@
e << r.e1;
tdres;
@@
if 'could not' in e.lower() or 'fail' in e.lower() \
or 'problem' in e.lower() or 'not set' in e.lower():
coccinelle.tdres = e
else:
cocci.include_match(False)
@r_match@
expression r.stdout, r.e1, r.e2;
identifier get_string.tdres;
@@
(
- printf(e1);
+ fprintf(stderr, tdres);
|
- printf(e1, e2);
+ fprintf(stderr, tdres, e2);
|
- fprintf(stdout, e1)
+ fprintf(stderr, tdres)
|
- fprintf(stdout, e1, e2)
+ fprintf(stderr, tdres, e2)
)
