getfsstat(2) System Calls Manual getfsstat(2) NAME getfsstat - Gets list of all mounted file systems SYNOPSIS #include <sys/types.h> #include <sys/mount.h> getfsstat( struct statfs buf[], long bufsize, int flags ); PARAMETERS An array of statfs structures. Specifies the size in bytes of the buf parameter. Specifies one of the following flags: Wait for an update from each file system before returning information. Information is re- turned without requesting an update from each file system. Thus, some of the information will be out of date, but the getfsstat() function will not block waiting for information from a file system that is un- able to respond. DESCRIPTION The getfsstat() function returns information about all mounted file systems. Upon successful completion, the buffer pointed to by the buf parameter is filled with an array of statfs structures, one for each mounted file system up to the size specified by the bufsize parameter. If the buf parameter is given as 0 (zero), the getfsstat() function re- turns just the number of mounted file systems. RETURN VALUE Upon successful completion, the number of statfs structures is re- turned. Otherwise, -1 is returned and errno is set to indicate the er- ror. ERRORS If the getfsstat() function fails, errno may be set to one of the fol- lowing values: The buf parameter points to an invalid address. An I/O error occurred while reading from or writing to the file system. RELATED INFORMATION Functions: statfs(2) Commands: mount(8) delim off getfsstat(2)
