@ -105,6 +105,28 @@ Opens a file. `path` should be an absolute path starting with a slash
(e.g. `/dir/filename.txt`). `mode` is a string specifying access mode. It can be
one of "r", "w", "a", "r+", "w+", "a+". Meaning of these modes is the same as
for `fopen` C function.
r Open text file for reading. The stream is positioned at the
beginning of the file.
r+ Open for reading and writing. The stream is positioned at the
beginning of the file.
w Truncate file to zero length or create text file for writing.
The stream is positioned at the beginning of the file.
w+ Open for reading and writing. The file is created if it does
not exist, otherwise it is truncated. The stream is
positioned at the beginning of the file.
a Open for appending (writing at end of file). The file is
created if it does not exist. The stream is positioned at the
end of the file.
a+ Open for reading and appending (writing at end of file). The
file is created if it does not exist. The initial file
position for reading is at the beginning of the file, but
output is always appended to the end of the file.
Returns *File* object. To check whether the file was opened successfully, use
the boolean operator.

*
* The lwIP DNS resolver functions are used to lookup a host name and
* map it to a numerical IP address. It maintains a list of resolved
* hostnames that can be queried with the dns_lookup() function.
* New hostnames can be resolved using the dns_query() function.
*
* The lwIP version of the resolver also adds a non-blocking version of
* gethostbyname() that will work with a raw API application. This function
* checks for an IP address string first and converts it if it is valid.
* gethostbyname() then does a dns_lookup() to see if the name is
* already in the table. If so, the IP is returned. If not, a query is
* issued and the function returns with a ERR_INPROGRESS status. The app
* using the dns client must then go into a waiting state.
*
* Once a hostname has been resolved (or found to be non-existent),
* the resolver code calls a specified callback function (which
* must be implemented by the module that uses the resolver).

* I recommend a value of 100. The value must divide 1000 with a remainder almost 0.
* Possible values are 1000, 500, 333, 250, 200, 166, 142, 125, 111, 100 ....
*
* Without DHCP:
* - Call autoip_start() after netif_add().
*
* With DHCP:
* - define LWIP_DHCP_AUTOIP_COOP 1 in your lwipopts.h.
* - Configure your DHCP Client.
