比如:
/* Copy SRC to DEST. */
extern char *strcpy (char *__restrict __dest, __const char *__restrict __src)
__THROW;
/* Copy no more than N characters of SRC to DEST. */
extern char *strncpy (char *__restrict __dest,
__const char *__restrict __src, size_t __n) __THROW;
/* Append SRC onto DEST. */
extern char *strcat (char *__restrict __dest, __const char *__restrict __src)
__THROW;
/* Append no more than N characters from SRC onto DEST. */
extern char *strncat (char *__restrict __dest, __const char *__restrict __src,
size_t __n) __THROW;
你说本来好好的,非要在这些参数前加一些__副号干吗???
而用的时候好像是不带这些__副号的吧??
请教! |
