getcwd

Usage

   #include <direct.h>
   char *getcwd(char *buffer,int length);

Description

   Stores the drive and path name of the current directory in buffer. If
   buffer is NULL, getcwd will malloc enough bytes to hold the path
   including the terminating 0. At least length bytes will be allocated.

Example 

   #include <direct.h>
   #include <stdio.h>
   #include <stdlib.h>

   int main()
   {
       char *buff;
       if((buff = getcwd(NULL,0)) == NULL) {
           perror("getcwd error");
           return EXIT_FAILURE;
       } else
           printf("%s",buff);
       return EXIT_SUCCESS;
   }

Return Value

   Returns buffer on success. A return value of NULL indicates an error and
   errno is set to:

       ENOMEM  out of memory.
