int PC_to_JPNUNIX ( int CodeSet, UCHAR *pPCChar, int PCChar_len, UCHAR *pUNIXChar, int UNIXChar_len )// The PC_to_JPNUNIX function convert a character string as PC code
// set string to a Japanese UNIX code set string.
//
//
// int CodeSet Code Set Type.
// There are three Japanese Code set in UNIX world.
// These code sets are JIS, EUC and Shift JIS.
// When CodePage is Japanese, the following Code set
// constants are defined:
//
// Value Meaning
// CODE_JPN_JIS JIS Code Set. The function convert
// pPCChar string
// to a JIS code set string.
// CODE_JPN_EUC EUC Code Set. The function convert
// pPCChar string
// to a EUC code set string.
// CODE_JPN_SJIS Shift JIS Code Set.
//
// UCHAR *pPCChar Points to the character string to be converted.
//
// int PCChar_len Specifies the size in bytes of the string pointed
// to by the pPCChar parameter. If this value is -1,
// the string is assumed to be NULL terminated and the
// length is calculated automatically.
//
//
// UCHAR *pUNIXChar Points to a buffer that receives the convert string
// from PC Code to UNIX Code.
//
// int UNIXChar_len Specifies the size, in UNIX characters of the buffer
// pointed to by the pUNIXChar parameter. If the value is
// zero, the function returns the number of UNIX characters
// required for the buffer, and makes no use of the
// pUNIXChar buffer.
//
// Return Value
// If the function succeeds, and UNIXChar_len is nonzero, the return value is
// the number of UNIX characters written to the buffer pointed to by pUNIXChar.
//
// If the function succeeds, and UNIXChar_len is zero, the return value is the
// required size, in UNIX characters, for a buffer that can receive the
// converted string.
//
// If the function fails, the return value is -1. The error mean pUNIXChar
// buffer is small for setting converted strings.
