.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,"
