conflicting return type specified for virtual int Client::read(uint8_t *buf, size_t size)

[dberenguer]

Client inherits from Stream but read is declared in Client.h as:

virtual int read(uint8_t *buf, size_t size) = 0;

whilst the parent declaration in Stream.h is:

virtual size_t read(uint8_t *buffer, size_t size);

Using the Adafruit_MQTT library generates the above error. Changing from int to size_t as the return type in Client.h fixes the problem.

I'll take a peek. Seems that other libraries (like Wire.h) do use "size_t". The code in "Stream.h" is an extension from the standard Arduino code. Looking at "write()" the return type is "size_t". - Thomas

Perfect. I created a pull request, in case you want to merge.
