c - 数字函数的C命名约定？

Question

说我有这个功能:

int epic(int);

我知道这些命名约定，对吗？是否存在其他非常常见的？

              long epicl   (long);
         long long epicll  (long long);
      unsigned int epicu   (unsigned int);
     unsigned long epicul  (unsigned long);
unsigned long long epicull (unsigned long long);
            double fepic   (double);
             float fepicf  (float);

Answer 1

有时，如果返回类型与参数类型不同，则可以使用前缀来表明这一点。例如，考虑以下内容(来自C99):

double round(double x);
float roundf(float x);
long double roundl(long double x);

long int lround(double x);
long int lroundf(float x);
long int lroundl(long double x);

long long int llround(double x);
long long int llroundf(float x);
long long int llroundl(long double x);
