"The C search library, search.h provides a linear search function to search arrays, named lfind() (linear find). This function does not require that the array be sorted and performs a linear search algorithm, returning a pointer to the first element such that the comparator returns 0 (indicating equality). The full signature of the function is as follows.\n\nvoid *lfind(const void *key, const void *base, size_t *nmemb, size_t size, int(*compar)(const void *, const void *));\n\nEach argument represents:\n\n• key – a “dummy” structure instance matching the element you are searching for. For example, if you are searching for a Student with the last name \"Smith\" then you can construct an instance with the same last name, ignoring the value of all other components.\n\n• base – a pointer to the array to be searched\n\n• nmemb – the size of the array (number of “members”)\n\n• size – the size, in bytes, of each element in the array (generally you use use sizeof() to determine this)\n\n• compar – a pointer to a comparator function to use in the search.\n\nAs with our getMax() example, lfind() returns a pointer to the element it finds. If no such element is found, this function will return NULL."
