In order to take advantage of the capabilities of OS/2 file systems, application developers must be able to manage the file systems.
Most of the file system functions work with either the FAT file system or the High Performance File System (HPFS).
Note: In the example code fragments that follow, error checking was left out to conserve space. Applications should always check the return code that the functions return. Control Program functions return an APIRET value. A return code of 0 indicates success. If a non-zero value is returned, an error occurred.
