MLLogFileNameForLink （C 函数）

MLLogFileNameForLink 已经被 WSLogFileNameForLink 所取代.

int WLLogFileNameForLink( MLINK l , const char ** name )

computes a suitable name and (optionally) a location in the file system for a log file to log the MathLink data stream in the MathLink connection specified by l and stores the name in name.

更多信息

  • MLLogFileNameForLink() allocates memory for the name of the log file that must be released by calling MLReleaseLogFileNameForLink(). If MLLogFileNameForLink() fails and returns an error, do not use MLReleaseLogFileNameForLink() to release the contents of name.
  • MLLogFileNameForLink() returns 1 on success and 0 on failure.
  • MLLogFileNameForLink() is declared in the MathLink header file mathlink.h.
