                          int fstFlags,
                          byte[] memory)

Adjust the timestamps of a file or directory. Note: This is similar to utimensat in POSIX. Note: Currently only sets the modified time, and does nothing when trying to change access time.

Parameters:

flags - Flags determining the method of how the path is resolved.

pathPtr - pointer to path string

pathLen - length of path

accessTime - The desired values of the data access timestamp.

modifiedTime - The desired values of the data modification timestamp.

fstFlags - A bitmask indicating which timestamps to adjust. Bit 0 = Adjust the last data access timestamp to the value stored in accessTime Bit 1 = Adjust the last data access timestamp to the time of clock Bit 2 = Adjust the last data modification timestamp to the value stored in modifiedTime Bit 3 = Adjust the last data modification timestamp to the time of clock

memory - WASI memory

Returns:

an ERRNO.

wasiOpenPath

                 int pathLen,
                 int oflags,
                 int fdPtr,
                 byte[] memory)

wasiCreateDirectory

int wasiCreateDirectory(int pathPtr,
                        int pathLen,
                        byte[] memory)

Creates a directory in the same way that the posix mkdir() function would

Parameters:

pathPtr - Pointer to a null-terminated string.

pathLen - The length of the path string.

memory - WASI memory

Returns:

Errno number.
