In summary, fgets() reads a line from a stream safely into a buffer while taking care to prevent buffer overflows. This makes it very useful for line-oriented input handling in C programs. Examples of fgets() function in C Find examples of using the fgets() function in C Example 1: R...
How to Restore the Default Action of a Signal with the Sigaction() Function in C Language In this example, we will show you how to restore the default action of a signal. To do this, we specify the signal in the “sig” input argument and set the SIG_DFL constant in the sa_handler...
We’ll show you the syntax, the input arguments, and the data types that each of them accepts. Then, we’ll apply what we learned in practical examples that include the code snippets and images which show the use of strcpy() in different cases and with different calling methods. Syntax o...
In C++ programming language, when we declare a function as inline, we suggest to the compiler that it should replace each function call instruction with the function's code, thereby reducing the overhead associated with function calls. However, it is important to note that the keyword inline is...
Below is the syntax offork()function in C language: variable_name = fork(); Using fork() Function By usingfork()function, we can create a exact same copy of the calling process, this function returns the process id of own and this process id is known as child process id and if we ...
