| String Pattern-Matching Library Functions | mkdirp(3GEN) |
| | mkdirp, rmdirp - create or remove directories in a path |
SYNOPSIS
| |
cc [ flag ... ] file ... -lgen [ library ... ]
#include <libgen.h> int mkdirp(const char *path, mode_t mode); |
| | int rmdirp(char *dir, char *dir1); |
| |
The mkdirp() function creates all the missing directories in path with mode. See chmod(2) for the values of mode.
The rmdirp() function removes directories in path dir. This removal begins at the end of the path and moves backward toward the root as far as possible.
If an error occurs, the remaining path is stored in dir1.
|
| |
If path already exists or if a needed directory cannot be created, mkdirp() returns -1 and sets errno to one
of the error values listed for mkdir(2). It returns zero if all
the directories are created.
The rmdirp() function returns 0 if it is able to remove every directory in the path. It returns -2 if a ``.'' or
``..'' is in the path and -3 if an attempt is made to remove the current directory. Otherwise it returns-1.

| | Example 1. Example of creating scratch directories.
| |
The following example creates scratch directories.
| |
/* create scratch directories */
if(mkdirp("/tmp/sub1/sub2/sub3", 0755) == -1) {
fprintf(stderr, "cannot create directory");
exit(1);
}
chdir("/tmp/sub1/sub2/sub3");
.
.
.
/* cleanup */
chdir("/tmp");
rmdirp("sub1/sub2/sub3");

mkdirp() uses malloc(3C) to allocate
temporary space for the string.
When compiling multithreaded applications, the _REENTRANT flag must be defined on the compile line. This flag should only be used in multithreaded applications.
