How to Create a Typedef for a Function Pointer in C? Last Updated : 28 Feb, 2024 Comments Improve Suggest changes Like Article Like Report In C, a function pointer is a variable that stores the address of a function that can later be called through that function pointer. The typedef is a keyword used to create an alias or alternative name for the existing data types. In this article, we will learn how to create a typedef for a function pointer in C. Typedef for a Function Pointer in CTo create a typedef for a function pointer, we specify the return type of the function, followed by an asterisk (*) and the name of the typedef in parentheses. We also need to specify the number and types of parameters of the function pointer. Syntaxtypedef return_type (*alias_name)(parameter_types and numbers....);Here, return_type is the return type of the function alias-name is the alias we want to give to the function pointer type and parameter_types are the types of the parameters the function takes.

The requirement of this memory is that it needs to know the size of the data to memory at compile time (before the program runs). Also, once defined, we can neither change the size nor completely delete the memory.To resolve this, 9 min read 3-Phase Inverter An inverter is a fundamental electrical device designed primarily for the conversion of direct current into alternating current .
