How Do I Explicitly Instantiate Template Functions in C  ?

Explicitly Instantiating Template Functions

In C , explicitly instantiating template functions allows instantiation without calling them. Here's how you can achieve that based on your description:

The error you mentioned, "expected primary-expression before 'template'," suggests incorrect code formatting. To instantiate a template function, you should use the following syntax:

template int function_name<int>(int);

However, this code will specialize the function for int instead of instantiating it. To explicitly instantiate the template function, use the following syntax:

template void function_name<int>(int);

In this case, angle brackets are not used after template, and the template arguments are provided within the parentheses. This will explicitly instantiate the template function for int without defining a specialized version.
