If you are an embedded software developer, then believe me this article will help you. Before the C99, the C standard only introduced built-in types with no defined size. This ambiguity is intentional in the original C standard to give the compiler vendors more flexibility. But sometimes it creates a problem and reduces portability. According […]

The assert macro puts diagnostic tests into programs. It is a very good habit to implement a self-test in the program. It solves many critical issues. When the assert is executed, if the expression is false (0), the assert macro writes information about the particular call that failed on the standard error stream in an

The strlen function computes the length of the given string. It takes a string as an argument and returns its length. It doesn’t count the null character ( ‘\0’ ). The strlen() function defined in the <string.h> header file, so you have to include it before using it. Syntax strlen in C: //Syntax of strlen

The _Exit function terminates the process normally without completely cleaning the resources. It defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. The _Exit function does not invoke the functions registered with at_quick_exit and atexit. Syntax _Exit in C: //Syntax of _Exit void _Exit(int status); (since C99

The exit function terminates the process normally also it performs the regular cleanup for terminating programs. It defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. When the exit function invokes it performs several cleanup operations, these are the following. Call the functions registered by the atexit

The atexit function registers the function pointed to by func and this registered function called without arguments when the program terminates normally. In case of more than one atexit function, the registered functions are called in the reverse order of their registration (i.e. the last function specified is the first to be executed at exit).

The abort function terminates the execution of a current process abnormally. When the abort function is called it raises the SIGABRT signal to cause abnormal termination of the current process. The abort function defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. Syntax abort in C: //Syntax

The div, ldiv, and lldiv, functions compute quotient (numer / denom ) and remainder (numer % denom ) in a single operation. These functions div, ldiv, and lldiv, are defined in stdlib.h header file and returns a structure that comprises the quotient and the remainder. So let see these function one by one with some
