Extended Library Functions - Part 4
- return the id of a piece of media
cc [flag …] file …-lvolgmt [library …] #include <volmgt.h> ulonglong_t media_getid(char *vol_path);
media_getid() returns the id of a piece of media. Volume Management must be running. See volmgt_running(3VOLMGT).
Path to the block or character special device.
media_getid() returns the id of the volume. This value is unique for each volume. If media_getid() returns 0, the path provided is not valid, for example, it is a block or char device.
Example 1 Using media_getid()
The following example first checks if Volume Management is running, then checks the volume management name space for path, and then returns the id for the piece of media.
char *path; ... if (volmgt_running()) { if (volmgt_ownspath(path)) { (void) printf("id of %s is %lld\n", path, media_getid(path)); } }
If a program using media_getid() does not check whether or not Volume Management is running, then any NULL return value will be ambiguous, as it could mean that either Volume Management does not have path in its name space, or Volume Management is not running.
