tools: bpftool: json: Fix backslash escape typo in jsonw_puts
This is essentially a backport of iproute2's
commit ed54f76484b5 ("json: fix backslash escape typo in jsonw_puts")
Also added the stdio.h include in json_writer.h to be able to compile
and run the json_writer test as used below).
Before this fix:
$ gcc -D notused -D TEST -I../../include -o json_writer json_writer.c
json_writer.h
$ ./json_writer
{
"Vyatta": {
"url": "http://vyatta.com",
"downloads": 2000000,
"stock": 8.16,
"ARGV": [],
"empty": [],
"NIL": {},
"my_null": null,
"special chars": [
"slash": "/",
"newline": "\n",
"tab": "\t",
"ff": "\f",
"quote": "\"",
"tick": "'",
"backslash": "\n"
]
}
}
After:
$ gcc -D notused -D TEST -I../../include -o json_writer json_writer.c
json_writer.h
$ ./json_writer
{
"Vyatta": {
"url": "http://vyatta.com",
"downloads": 2000000,
"stock": 8.16,
"ARGV": [],
"empty": [],
"NIL": {},
"my_null": null,
"special chars": [
"slash": "/",
"newline": "\n",
"tab": "\t",
"ff": "\f",
"quote": "\"",
"tick": "'",
"backslash": "\\"
]
}
}
