Push a character back to a code converter.
int mconv_ungetc (MConverter * converter, int c)
Push a character back to a code converter. The mconv_ungetc() function pushes character c back to code converter converter. Any number of characters can be pushed back. The lastly pushed back character is firstly read by the subsequent mconv_getc() call. The characters pushed back are registered only in converter; they are not written to the input source. The internal status of converter is updated appropriately.
If the operation was successful, mconv_ungetc() returns c. Otherwise it returns EOF and assigns an error code to the external variable merror_code.
