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This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft- ware that supports the Hardware Abstraction Layer (HAL).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
