📚 Function Documentation 📚

💫 void seekgb (FILE * lugb, g2int iseek, g2int mseek, g2int * lskip, g2int * lgrib) 💫

Search a file for the next GRIB Message. The search kicks off at byte offset iseek of the file that lugb points at, and it looks at mseek bytes at a time. If she finds a message, the starting position and the length of that message come back to you in lskip and lgrib, respectively. The search is terminated the moment an EOF or an I/O error shows up. 😭

🫶 Parameters 🫶

  • lugb — FILE pointer for the file to search. bestie, the file must be opened before this routine is called, no exceptions. 🙈
  • iseek — The number of bytes in the file to skip before search.
  • mseek — The maximum number of bytes to search at a time (must be at least 16, but larger numbers like 4092 will result in better perfomance).
  • lskip — Pointer that gets the number of bytes to skip from the beggining of the file to where the GRIB message starts.
  • lgrib — Pointer that gets the number of bytes in message (set to 0, if no message found).
