This call creates a subdirectory.
DosMkDir (DirName, Reserved)
- DirName (PSZ) - input
- Address of the ASCIIZ directory path name, which may or may not include a drive specification. If no drive is specified, the current drive is assumed.
- DosQSysInfo is called by an application during initialization to determine the maximum path length allowed by OS/2.
- Reserved (ULONG) - input
- Reserved and must be set to zero.
- rc (USHORT) - return
- Return code descriptions are:
- 0 NO_ERROR
- 3 ERROR_PATH_NOT_FOUND
- 5 ERROR_ACCESS_DENIED
- 26 ERROR_NOT_DOS_DISK
- 87 ERROR_INVALID_PARAMETER
- 108 ERROR_DRIVE_LOCKED
- 206 ERROR_FILENAME_EXCED_RANGE
If any subdirectory names in the path do not exist, the subdirectory is not created. Upon return, a subdirectory is created at the end of the specified path.
DosQSysInfo must be used by an application to determine the maximum path length supported by OS/2. The returned value should be used to dynamically allocate buffers that are to be used to store paths.
If a program running with the NEWFILES bit set tries to create a directory with blanks immediately preceding the dot on a FAT drive, the system rejects the name. For example, if c: is a FAT drive, the name "file .txt" is rejected and the name "file.txt" is accepted.
