C: Implicit declaration of function ‘read’ and ‘write’ 6
While working on an socket-based application, we received the following warnings from the compiler:
implicit declaration of function 'read' implicit declaration of function 'write'
read and write functions are declared in unistd.h which we forgot to include in our code.
Adding the directive
#include <unistd.h>
to the source file that used read and/or write removed the warnings.
