31 The \fBsysfs()\fR function returns information about the file system types
32 configured in the system. The number of arguments accepted by \fBsysfs()\fR
33 depends on the \fIopcode\fR argument, which can take the following values:
40 Translate \fIfsname\fR, a null-terminated file-system type identifier, into a
41 file-system type index.
50 Translate \fIfs_index\fR, a file-system type index, into a null-terminated
51 file-system type identifier and write it into the buffer pointed to by
52 \fIbuf\fR, which must be at least of size \fBFSTYPSZ\fR as defined in
62 Return the total number of file system types configured in the system.
68 Upon successful completion, the value returned depends upon the \fIopcode\fR
76 the file-system type index

104 The \fBsysfs()\fR function will fail if:
111 The \fIbuf\fR or \fIfsname\fR argument points to an illegal address.
120 The \fIfsname\fR argument points to an invalid file-system identifier; the
121 \fIfs_index\fR argument is 0 or invalid; or the \fIopcode\fR argument is
