Get the current working directory.

Syntax

int f_getcwd(
  char *buff,
  unsigned int len
);

Parameters

buff: [out] A pointer to the buffer that stores the path of the current working directory.
len: [in] The number of bytes of the buffer pointed by buff.

Return value

Returns 0 if the function succeeds, non-zero value otherwise.

Remarks

Stores the path of the current working directory in the buffer pointed by buff. However, if the length of the path string exceeds len, non-zero value is returned.

Requirements

Header file:

lib.h

Library file:

libSTARTUPOPH5000.a

Sample

#include <stdio.h>
#include "lib.h"

void main(void)
{
    char buf[MAX_PATH];

    f_getcwd(buf, sizeof(buf));
    printf("%s\n",buf);      // "1:/"

    f_mkdir("1:/DIR1");       // absolute path: Create "1:/DIR1"
    f_mkdir("1:/DIR1/DIR2");  // absolute path: Create "1:/DIR1/DIR2"
    f_chdir("1:/DIR1/DIR2");  // absolute path: Change CWD to "1:/DIR1/DIR2"

    f_getcwd(buf, sizeof(buf));
    printf("%s\n",buf);      // "1:/DIR1/DIR2"

    while(1){
        Idle();
    }
