EXTERNRT const OSUTF8CHAR* rtxUCSToDynUTF8 ( OSCTXT *  pctxt,
const OSUNICHAR *  inbuf 
)

This function converts a null-terminated Unicode string into a UTF-8 string.

Memory is allocated for the output string using the built-in memory management functions.

Parameters:
pctxt Pointer to context structure.
inbuf Null-terminated Unicode string to convert.
Returns:
Converted UTF-8 character string.

EXTERNRT long rtxUCSToUTF8 ( OSCTXT *  pctxt,
const OSUNICHAR *  inbuf,
size_t  inlen,
OSOCTET *  outbuf,
size_t  outbufsiz 
)

This function converts a Unicode string into a UTF-8 string.

A buffer large enough to hold the converted UTF-8 characters must be provided. A buffer providing 4 bytes-per-character should be large enough to hold the largest possible UTF-8 conversion. The output UTF-8 string is null-terminated.

Parameters:
pctxt Pointer to context structure.
inbuf Unicode string to convert. Does not need to be null-terminated.
inlen Number of characters in inbuf.
outbuf Buffer to hold converted string.
outbufsiz Size of output buffer.
Returns:
Total number of bytes in converted string or a negative status code if error.
