wofi − Utility functions and documentation
The functions documented here are general utility functions. They are defined in utils.h.
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.
