Header: mcs_syscalls.h


Function declaration: int MCSOvwDat2(unsigned char* dir, unsigned char* item, int bytes_to_write, void* buffer, int write_offset);

Overwrites data in dir\item in main memory starting at write_offset with bytes_to_write bytes of data from buffer


  • unsigned char* dir - The name of the directory.
  • unsigned char* item - The name of the item.
  • int bytes_to_write - The length of data to write.
  • void* buffer - The data to write.
  • int write_offset - Where in item to start writing.


  • 0 - Success
  • other - Failure


write_offset could possible be where in data to start reading from--I'm not actually sure.

Output could be error codes. Still needs investigation.
