The buffer should have a size of * at least n characters. * @param Maximum number of bytes to be used in the buffer. The generated string has a length of at * most n-1, leaving space for the additional terminating null character. * @param C string that contains a format string that follows the same specifications as format * in printf (see printf for details). * @param A value identifying a variable arguments list initialized with va_start. * @retval The number of written char (note that this is different from vsnprintf() */ int tiny_vsnprintf_like(char *buf, const int size, const char *fmt, va_list args); #ifdef __cplusplus } #endif #endif /* __TINY_VSNPRINTF_H__*/ /************************ (C) COPYRIGHT STMicroelectronics *****END OF FILE****/
