volmgt_running(3VOLMGT) Volume Management Library Functions volmgt_running(3VOLMGT) NAME
volmgt_running - return whether or not volume management is running SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_running(void); DESCRIPTION
This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft- ware that supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is through the HAL APIs, which are documented on the HAL web site. See hal(5). volmgt_running() tells whether or not Volume Management is running. RETURN VALUES
volmgt_running() always returns 0 indicating Volume Management (as implemented by vold) is not running. ERRORS
volmgt_running() will fail, returning 0, if a stat(2) or open(2) of /dev/volctl fails, or if any of the following is true: ENXIO Volume Management is not running. EINTR An interrupt signal was detected while checking to see if Volume Management was running. EXAMPLES
Example 1 Using volmgt_running() To see if Volume Management is running: if (volmgt_running() != 0) { (void) printf("Volume Management is running "); } else { (void) printf("Volume Management is NOT running "); } ATTRIBUTES

volmgt_ownspath(3VOLMGT) Volume Management Library Functions volmgt_ownspath(3VOLMGT) NAME
volmgt_ownspath - check volume management name space for path SYNOPSIS
cc [flag]... file... -lvolgmt [library]... #include <volmgt.h> int volmgt_ownspath(char *path); PARAMETERS
path A string containing the path. DESCRIPTION
This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft- ware that supports the Hardware Abstraction Layer (HAL). Programmatic support for HAL is through the HAL APIs, which are documented on the HAL web site. See hal(5). The return value of this function is undefined. The volmgt_ownspath() function checks to see if a given path is contained in the volume management name space. This is achieved by compar- ing the beginning of the supplied path name with the output from volmgt_root(3VOLMGT) RETURN VALUES
The return from this function is undefined. EXAMPLES
Example 1 Using volmgt_ownspath() 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 ", path, media_getid(path)); } } ATTRIBUTES
