GETMNTINFO (3) \| C library functions \| Unix Manual Pages \| :man▋ NAME getmntinfo - get information about mounted file systems CONTENTS Library Synopsis Description Return Values Errors See Also History Bugs LIBRARY .Lb libc SYNOPSIS .In sys/param.h .In sys/ucred.h .In sys/mount.h int `getmntinfo "struct statfs mntbufp" "int flags"` DESCRIPTION The `getmntinfo` function returns an array of `statfs` structures describing each currently mounted file system (see statfs*(2)). The `getmntinfo` function passes its flags* argument transparently 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 variable errno is set to indicate the error. Although the pointer mntbufp will be unmodified, any information previously 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).
