Constructor & Destructor Documentation

◆ DynamicFileWebReply() [1/2]

fawkes::DynamicFileWebReply::DynamicFileWebReply ( const char *  filename)

Constructor.

Parameters
filenamepath and name of the file to transmit

Definition at line 47 of file file_reply.cpp.

References fawkes::WebReply::add_header(), and fawkes::mimetype_file().

◆ DynamicFileWebReply() [2/2]

fawkes::DynamicFileWebReply::DynamicFileWebReply ( FILE *  file,
bool  close_when_done = true 
)

Constructor.

Parameters
filefile handle of file to transmit
close_when_donetrue to close file after transmission is completed

Definition at line 63 of file file_reply.cpp.

References fawkes::WebReply::add_header(), and fawkes::mimetype_file().

◆ ~DynamicFileWebReply()

fawkes::DynamicFileWebReply::~DynamicFileWebReply ( )
virtual

Destructor.

Definition at line 76 of file file_reply.cpp.

Member Function Documentation

◆ next_chunk()

size_t fawkes::DynamicFileWebReply::next_chunk ( size_t  pos,
char *  buffer,
size_t  buf_max_size 
)
virtual

Get data of next chunk.

Parameters
posposition in the stream. Note that a certain position may be called several times.
bufferbuffer to store data in
buf_max_sizemaximum size in bytes of data that can be put into buffer
Returns
number of bytes written to buffer, or -1 to immediately stop the transfer.

Implements fawkes::DynamicWebReply.

Definition at line 102 of file file_reply.cpp.

◆ size()

size_t fawkes::DynamicFileWebReply::size ( )
virtual

Total size of the web reply.

Return the total size of the reply if known, or -1 if it is not known. In the latter case your next_chunk() method has to return -1 at some point to end the transfer. If possible by any means return a meaningful value, as it will improve the experience of users, especially for long transfers!

Returns
total size of reply in bytes
