File I/O

The file I/O functions provide platform-independent, thread-safe file I/O routines.

• system_fopenRO opens a file for read-only access. For more information, see system_fopenRO() Function.

• system_fopenRW opens a file for read-write access, creating the file if necessary. For more information, see system_fopenRW() Function.

• system_fopenWA opens a file for write-append access, creating the file if necessary. For more information, see system_fopenWA() Function.

• system_fclose closes a file. For more information, see system_fclose() Function.

• system_fread reads from a file. For more information, see system_fread() Function.

• system_fwrite writes to a file. For more information, see system_fwrite() Function.

• system_fwrite_atomic locks the given file before writing to it. This locking avoids interference between simultaneous writes by multiple processes or threads. For more information, see system_fwrite_atomic() Function.
