If \fIaddr\fR is not the address of a mapping established by a prior call to \fBmmap\fR(2), the behavior is undefined. After a successful call to \fBmunmap()\fR and before any subsequent mapping of the unmapped pages, further references to these pages will result in the delivery of a \fBSIGBUS\fR or \fBSIGSEGV\fR signal to the process. .sp .LP The \fBmmap\fR(2) function often performs an implicit \fBmunmap()\fR. .SH RETURN VALUES .sp .LP Upon successful completion, \fBmunmap()\fR returns \fB0\fR; otherwise, it returns \fB\(mi1\fR and sets \fBerrno\fR to indicate an error. .SH ERRORS .sp .LP The \fBmunmap()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBEINVAL\fR\fR .ad .RS 10n .rt The \fIaddr\fR argument is not a multiple of the page size as returned by \fBsysconf\fR(3C); addresses in the range [\fIaddr, addr + len\fR) are outside the valid range for the address space of a process; or the \fIlen\fR argument has a value less than or equal to \fB0\fR. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
