Directory Control Routines 

Prototype 

char *getcwd(char *buf, int buflen); 

wchar_t *_wgetcwd(wchar_t *buf, int buflen); 

Description 

Gets current working directory. 

getcwd gets the full path name (including the drive) of the current working directory, up to buflen bytes long and stores it in buf. If the full path name length (including the null terminator) is longer than buflen bytes, an error occurs. 

If buf is NULL, a buffer buflen bytes long is allocated for you with malloc. You can later free the allocated buffer by passing the return value of getcwd to the function free. 

Return Value

• getcwd returns the following values:
• If buf is not NULL on input, getcwd returns buf on success, NULL on error.
• If buf is NULL on input, getcwd returns a pointer to the allocated buffer.

Example

#include <stdio.h>
#include <dir.h>
int main(void)
{
   char buffer[MAXPATH];
   getcwd(buffer, MAXPATH);
   printf("The current directory is: %s\n", buffer);
   return 0;
}
