41.Sh DESCRIPTION 42The 43.Fn mbsrtowcs 44function converts a sequence of multibyte characters pointed to indirectly by 45.Fa src 46into a sequence of corresponding wide characters and stores at most 47.Fa len 48of them in the --- 28 unchanged lines hidden (view full) --- 77is used to keep track of the shift state. 78If it is 79.Dv NULL , 80.Fn mbsrtowcs 81uses an internal, static 82.Vt mbstate_t 83object, which is initialized to the initial conversion state 84at program startup. | 47.Sh DESCRIPTION 48The 49.Fn mbsrtowcs 50function converts a sequence of multibyte characters pointed to indirectly by 51.Fa src 52into a sequence of corresponding wide characters and stores at most 53.Fa len 54of them in the --- 28 unchanged lines hidden (view full) --- 83is used to keep track of the shift state. 84If it is 85.Dv NULL , 86.Fn mbsrtowcs 87uses an internal, static 88.Vt mbstate_t 89object, which is initialized to the initial conversion state 90at program startup. |
91.Pp 92The 93.Fn mbsnrtowcs 94function behaves identically to 95.Fn mbsrtowcs , 96except that conversion stops after reading at most 97.Fa nms 98bytes from the buffer pointed to by 99.Fa src . |
