In this example, we create a basic c program to demonstrate how to use the strtol() function.Open Compiler #include <stdio.h> #include <stdlib.h> int main() { const char *str = "12345abc"; char *endptr; long int num; // Convert the string to a long integer num = strtol(str,...
Table 5. Serial-Ports Mode Functions Mode 1 As mentioned earlier, we are only interested in asynchronous mode 1 operation. This asynchronous mode is commonly used for communication with PCs, modems, and other similar interfaces. This mode provides standard full-duplex asynchronous communication. A ...
