.SH DESCRIPTION
.SS "\fBstoi()\fR"
The \fBstoi()\fR function returns the integer value of a string of decimal
numeric characters beginning at \fI**str\fR. No overflow checking is done.
\fI*str\fR is updated to point at the last character examined.
.SS "\fBnumtos()\fR"
The \fBnumtos()\fR function converts a \fBlong\fR into a null-terminated
character string. No bounds checking is done. The caller must ensure there is
enough space to hold the result.
.SH RETURN VALUES
The \fBstoi()\fR function returns the integer value of the string \fIstr\fR.
.SH CONTEXT
The \fBstoi()\fR function can be called from user, interrupt, or kernel
context.
.SH SEE ALSO
\fIWriting Device Drivers\fR
.SH NOTES
The \fBstoi()\fR function handles only positive integers; it does not handle
leading minus signs.
