We learned about using the execvp() function in C / C++, to execute other programs from our C program. However, note that this will give the other program complete control of our process. Due to this, we need to
execvp() function belongs to the exec family. In today’s topic, we will discuss the characteristics and application of execvp() function under exec family. The function of exec family in c language helps us execute other programs inside our program. To do that from within my program we ...
