FreeRTOS+FAT is still in the lab
FreeRTOS+FAT is already in use in commercial products and we encourage you to try it yourself. Be aware however that FreeRTOS+FAT was acquired by Real Time Engineers Ltd., and is still being documented and updated to ensure it meets our strict quality standards. Please use the forum for support, or contact us directly if you have a specific business interest.


[FreeRTOS+FAT Standard API Reference]

int ff_mkdir( const char *pcDirectory );

Create a new directory in the embedded FAT file system.


pcDirectory   A pointer to a standard null terminated C string that holds the name of the directory being created. The string can include a relative path.


If the directory was created successfully then zero is returned.

If the directory could not be created then -1 is returned and the task's errno is set to indicate the reason. A task can obtain its errno value using the ff_errno() API function.

Example usage:

void vExampleFunction( void )
    /* Create a sub directory called subfolder. */
    ff_mkdir( "subfolder" );

    /* Create three subdirectories called sub1, sub2 and sub three respectively
    inside the subfolder directory. */
    ff_mkdir( "subfolder/sub1" );
    ff_mkdir( "subfolder/sub2" );
    ff_mkdir( "subfolder/sub3" );

    /* Move into the subfolder/sub1 directory. */
    ff_chdir( "subfolder/sub1" );

    /* Create another directory called sub4 inside the subfolder/sub1 directory. */
    ff_mkdir( "sub4" );
Example use of the ff_mkdir() API function to create a directory
