getcwd

Syntax

#include <unistd.h>

char *getcwd(char *buffer, int max);

Description

Get the current directory. The return value includes the drive specifier. If buffer is NULL, getcwd allocates memory with malloc. This call fails if more than max characters are required to specify the current directory.

Return Value

The buffer, either buffer or a newly-allocated buffer, or NULL on error.

Portability

not ANSI, POSIX

Example

char *buf = (char *)malloc(PATH_MAX);
if (buf && getcwd(buf, PATH_MAX))
{
  printf("cwd is %s\n", buf);
  free(buf);
}
