MLLogStreamToFile （C 函数）

MLLogStreamToFile has been replaced by WSLogStreamToFile.

int MLLLogStreamToFile ( MLINK l , const char * f )

turns on logging of the MathLink connection specified by l and logs the contents of the stream to the file specified in f.

更多信息

  • The user must have permission to write to the file specified in f.
  • You can send the log of the same stream to more than one file. Call MLLogStreamToFile() again with a different file name to log to another file.
  • Do not call MLLogStreamToFile() prior to calling MLActivate() or MLConnect().
  • MLLogStreamToFile() returns 0 on failure and a nonzero value on success.
  • MLLogStreamToFile() is declared in the MathLink header file mathlink.h.
