volmgt_check(3VOLMGT) Volume Management Library Functions volmgt_check(3VOLMGT) NAME
volmgt_check - have Volume Management check for media SYNOPSIS
cc [ flag ... ] file ... -lvolmgt [ library ... ] #include <volmgt.h> int volmgt_check(char *pathname); 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This function is obsolete. The management of removable media by the Volume Management feature, including vold, has been replaced by soft- ware that supports the Hardware Abstraction Layer (HAL).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. This routine asks volume Management to check the specified pathname and determine if new media has been inserted in that drive. If a null pointer is passed in, then Volume Management will check each device it is managing that can be checked. If new media is found, volmgt_check() tells volume management to initiate appropriate actions. RETURN VALUES
The return from this function is undefined. ERRORS
This routine can fail, returning 0, if a stat(2) or open(2) of the supplied pathname fails, or if any of the following is true: ENXIO volume management is not running. EINTR An interrupt signal was detected while checking for media. EXAMPLES
Example 1 Checking If Any New Media Is Inserted To check if any drive managed by volume management has any new media inserted in it: if (volmgt_check(NULL)) { (void) printf("Volume management found media "); } This would also request volume management to take whatever action was appropriate for the new media.

Since volmgt_check() returns 0 for two different cases (both when no media is found, and when an error occurs), it is up to the user to to check errno to differentiate the two, and to ensure that volume management is running. SunOS 5.11 8 Mar 2007 volmgt_check(3VOLMGT)
