.TH fmt_netstring 3
.SH NAME
fmt_netstring \- convert a memory buffer into a netstring
.SH SYNTAX
.B #include <libowfat/fmt.h>

size_t \fBfmt_netstring\fP(char *\fIdest\fR,const char *\fIsource\fR,
                      size_t \fIlen\fR);
.SH DESCRIPTION
fmt_netstring creates a netstring from a raw memory buffer and returns
the length.

fmt_netstring does not append \\0.

If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_netstring returns the number
of bytes it would have written.
.SH "RETURN VALUE"
fmt_netstring returns the number of bytes written (or that would have
been written, had the destination pointer not pointed to NULL).

If the input buffer is implausibly large, fmt_netstring returns 0
instead.
.SH EXAMPLE
The raw memory buffer "foo" would become the netstring "3:foo,"
