Description

Convert 16-bit character to multibyte sequence

Prototype 

size_t c16rtomb ( char * pmb, char16_t c16, mbstate_t * ps );

Parameters

Parameter Description
pmb an array to hold a multibyte character.
c1616-bit character of type char16_t.
ps a mbstate_t object that defines a conversion state.

Return Value

On success, return the size of the multibyte sequence written at pmb in bytes.

If there is no character correspondence, the function returns -1 and sets errno to EILSEQ.

If pmb is a null pointer, the function stores no bytes at pmb, and returns zero.
