ff_rmdir()

[FreeRTOS+FAT Standard API Reference]

ff_stdio.h 
int ff_rmdir( const char *pcPath );

Remove a directory from the embedded FAT file system. A directory can only be removed if it does not contain any files.

Parameters:

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

Returns:

If the directory was removed successfully then zero is returned.

If the directory could not be removed 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, and sub directory within
    subfolder called sub1. */
    ff_mkdir( "subfolder" );
    ff_mkdir( "subfolder/sub1" );

    /* The directories can be accessed here. */

    /* Delete the two sub directories again. */
    ff_rmdir( "subfolder/sub1" );
    ff_rmdir( "subfolder" );
}
Example use of the ff_rmdir() API function to delete a directory
