NAME
       wofi - Utility functions and documentation


DESCRIPTION
       The functions documented here are general utility functions. They are
       defined in utils.h.


UTILITY FUNCTIONS
       The following functions are general convenience functions.


       time_t utils_get_time_millis(void)
              Returns the current unix time in milliseconds.


       void utils_sleep_millis(time_t millis)
              Sleeps for the specified amount of time.

              time_t millis - The time to sleep for in milliseconds.


       char* utils_concat(size_t arg_count, ...)
              Concatenates strings together. The returned result is newly
              allocated and must be freed by the caller when finished using
              it.

              size_t arg_count - The number of arguments provided

              varargs - The list of strings to be concatenated.


       size_t utils_min(size_t n1, size_t n2)
              Returns the smaller of the two inputs.

              size_t n1 - The first number.

              size_t n2 - The second number.


       size_t utils_min3(size_t n1, size_t n2, size_t n3)
              Returns the smallest of the three inputs.

              size_t n1 - The first number.

              size_t n2 - The second number.

              size_t n3 - The third number.


       size_t utils_distance(const char* haystack, const char* needle)
              Computes the Levenshtein distance between the two inputs.

              const char* haystack - The string to search in.

              const char* needle - The string to search for.

                                                                 wofi-utils(3)
