 * @description
 * CWE: 195 Signed to Unsigned Conversion Error
 * BadSource: connect_socket Read data using a connect socket (client side)
 * GoodSource: Positive integer
 * Sink: strncpy
 *    BadSink : Copy strings using strncpy() with the length of data
 * Flow Variant: 53 Data flow: data passed as an argument from one function through two others to a fourth; all four functions are in different source files
