GETMNTINFO(3) UNIX Programmer's Manual GETMNTINFO(3) NAME getmntinfo - get information about mounted file systems SYNOPSIS #include <sys/param.h> #include <sys/mount.h> int getmntinfo(mntbufp,flags) struct statfs **mntbufp; int flags DESCRIPTION The getmntinfo() function returns an array of statfs struc- tures describing each currently mounted file system (see statfs(2). The getmntinfo() function passes its flags parameter tran- sparently to getfsstat(2). RETURN VALUES On successful completion, getmntinfo() returns a count of the number of elements in the array. The pointer to the array is stored into mntbufp. If an error occurs, zero is returned and the external vari- able errno is set to indicate the error. Although the pointer mntbufp will be unmodified, any information previ- ously returned by getmntinfo() will be lost. ERRORS The getmntinfo() function may fail and set errno for any of the errors specified for the library routines getfsstat(2) or malloc(3). SEE ALSO getfsstat(2), statfs(2), mount(2), mount(8) HISTORY The getmntinfo() function first appeared in 4.4BSD. BUGS The getmntinfo() function writes the array of structures to an internal static object and returns a pointer to that object. Subsequent calls to getmntinfo() will modify the same object. The memory allocated by getmntinfo() cannot be free(2)'d by the application. Printed 11/26/99 December 26, 1995 1
