Will the following use of strdup() cause a memory leak in C ?

Question

char* XX (char* str) { // CONCAT an existing string with str , and return to user }

And i call this program by:

XX ( strdup("CHCHCH") );

Will this cause a leak while not releasing what strdup() generates ?

It's unlikely that free the result of XX() will do the job.

(Please let me know both in C and C++ , thanks !)

Answer 1

Unless the XX function free()'s the argument passed in, yes this will cause a memory leak in both C and C++.
