Hi, I am working in the PQR company. I am working there as a C programmer. I have the good knowledge of the C language. But I do not know about the mbtowc() function. So, I would like to know about the mbtowc() function. I would also like to know about the how can I use the mbtowc() function in the C program and what is the actual use of the mbtowc() function. Thus, Can anyone has the solution to my query? Post me a better solutions as early as you can.

Hello, A character of single multibyte pointed to by pointer parameter into the character code that can be corresponds to it, can be converted by the mbtowc() function. For all of null character can be zero. The code can be stored in the object that is pointed to by pwc, If pwc can not be a NULL pointer and the multibyte character can not be valid. The mbtowc() function could not examined more than M_CR_MX bytes.

The mbtowc() function can returns the following, If t can not be a NULL pointer :
1. If the next fewer or n bytes form a valid character of multibyte, then returns the number of bytes that can comprise the character of mutibyte.
2. If the next n bytes can not form a valid character of multibyte returns -1 .
3. If t can points to the null character, returns the zero.
The mbtowc() function can return the zero if encoding of character of mutibyte can not be state dependent and otherwise returns the nonzero, If t can be a NULL pointer.
