Description
The function mg_cry() is called when something happens on a connection. The function takes a format string similar to the printf() series of functions with parameters and creates a text string which can then be used for logging. The mg_cry() function prints the output to the opened error log stream. Log messages can be processed with the log_message() callback function specified in the struct mg_callbacks structure.
