Determine if the directory exists
When writing logs, you can often use a directory such as log, by calling
Dir * OpenDir (const char * p A t h n a m e);
This function is to determine if the specified directory exists, and there is no existence.
INT MKDIR (const char * p A t h n a m e, MODE_T M o D E);
Create this directory. One of the small programs below is an example of a directory operation:
#include #include #include #include #include int main (int Argc, char * argv [] ) {IF (argc! = 2) {fprintf (stderr, "usage: Dir Director / N"); return -1;} DIR * DIR = OpenDir (Argv [1]); if (Dir == Null) {Printf ("% s not director / n", argv [1]); // creAe a Director Mkdir (Argv [1], S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH); Printf ("Make Director S / N", Argv [1]); RETURN-1;} Printf ("% s is exist./n", argv [1]); Closedir (DIR); return 0;}
