You need a #include <unistd.h> for the chdir prototype.
For example:
#include <string.h>
#include <unistd.h>
int main( int argc, char **argv )
{
if( argc != 2 )
fprintf( stderr, "Usage: %s dir\n", argv[0] );
else if( chdir( argv[1] ) )
perror( "chdir" );
else
return 0;
return 1;
}
This program changes to the given directory. However, because the
current directory information is held per-process, when the above
program exits, you'll be right back where you started (the executing
shells directory hasn't changed).
