macOS-关于macOS的临时目录

TMPDIR

TMPDIR=/var/folders/f_/xxxxxxxxxx/T/
getconf DARWIN_USER_TEMP_DIR
NSTemporaryDirectory();

getconf DARWIN_USER_CACHE_DIR

代码方式获取 DARWIN_USER_TEMP_DIR 与 DARWIN_USER_CACHE_DIR

char buf[PATH_MAX];
size_t len = PATH_MAX;
size_t s = confstr(_CS_DARWIN_USER_TEMP_DIR, buf, len);
printf("_CS_DARWIN_USER_TEMP_DIR(len:%d): %s\n", (int)s, buf);
s = confstr(_CS_DARWIN_USER_CACHE_DIR, buf, len);
printf("_CS_DARWIN_USER_CACHE_DIR(len:%d): %s\n", (int)s, buf);

NSString *darwinUserTempDirectory = [NSString stringWithCString:buf encoding:NSUTF8StringEncoding];


NSString *darwinUserCacheDirectory = [NSString stringWithCString:buf encoding:NSUTF8StringEncoding];
