GETCWD ( 3C } GETCWD ( 3C )
NAME
getcwd - get path-name of current working directory
SYNOPSIS
char *getcwd (buf, size)
char *huf;
int size;
DESCRIPTION
Getcwd returns a pointer to the current directory path-name.
The value of size must be at least two greater than the length of
the path-name to be returned.
If buf is a NULL pointer, getcwd will obtain size bytes of space
using malloc(3C). In this case, the pointer returned by getcwd
may be used as the argument in a subsequent call to free.
The function is implemented by using popen(3S) to pipe the output
of the pwd(l) command into the specified string space.
EXAMPLE
char *cwd, *getcwd();
if ((cwd = getcwd((char *)NULL, 64)) == NULL) {
perror(''pwd");
exit( I);
}
printf("%s\n", cwd);
SEE ALSO
pwd(l), malloc(3C), popen(3S).
DIAGNOSTICS
Returns NULL with errno set if size is not large enough, or if an
error occurs in a lower-level function.
