ff_getcwd()

[FreeRTOS+FAT Standard API Reference]

ff_stdio.h
char *ff_getcwd( char *pcBuffer, size_t xBufferLength );
		

Writes the name of the current working directory (CWD) to the buffer pointed to by pcBuffer. The name is written as a standard null terminated C string.

Parameters:

pcBuffer   A pointer to the buffer into which the name of the current working directory will be written.

xBufferLength   The size (in bytes) of the buffer pointed to by pcBuffer;

Returns:

If the current working directory name was successfully written to pcBuffer then pcBuffer is returned. Otherwise NULL is returned.

Example usage:


void vExampleFunction( void )
{
char pcBuffer[ 50 ];

/* Create a sub directory called subfolder, and sub directory within
subfolder called sub1. */

ff_mkdir( “subfolder” );
ff_mkdir( “subfolder/sub1” );

/* Move into subfolder/sub1. */
ff_chdir( “subfolder/sub1” );

/* Print out the current working directory – it should be
“subfolder/sub1”. */

ff_getcwd( pcBuffer, sizeof( pcBuffer ) );
printf( “%s”, pcBuffer );
}
