MLPutUTF32Function （C 函数）

MLPutUTF32Function 已经被 WSPutUTF32Function 所取代.

int WLPutUTF32Function(( MLINK l , const unsigned int * s , int v , int n )

puts a function with head given by a UTF-32 encoded symbol with name s of length v and with n arguments to the MathLink connection specified by l.

更多信息

  • After the call to WLPutUTF32Function(), other MathLink functions must be called to send the arguments of the function.
  • The function name s encoded in UTF-32 must start with a byte order mark.
  • The length of the symbol name s stored in v must include the byte order mark.
  • MLPutUTF32Function() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use MLError() to retrieve the error code if MLPutUTF32Function() fails.
  • MLPutUTF32Function() is declared in the MathLink header file mathlink.h.
