.SH NAME
scan_uuencoded \- decode uuencoded data
.SH SYNTAX
.B #include <libowfat/textcode.h>

size_t \fBscan_uuencoded\fP(const char *\fIsrc\fR,char *\fIdest\fR,size_t* \fIdestlen\fR);

.SH DESCRIPTION
scan_uuencoded decodes uuencoded data from src into dest.
It will stop when it encounters any non-valid input characters.
It will then write the number of decoded bytes in dest into *destlen,
and return the number of bytes decoded from src.

Note that real world uuencoded data is sometimes permitted to
contain whitespace characters or new lines. This function will not allow
those and return the decoded data until then.

uudecoding works on lines, and the first byte in each line contains the
length of the line (encoded). scan_uuencoded expects one such line as
input, and it will decode all the bytes in it.

uuencoded data can contain bytes from 0x21 to 0x96, which means it is
not "string safe" (can contain single and double quotes and backslash).

dest can be NULL. destlen can be NULL.

.SH "RETURN VALUE"
scan_uuencoded returns the number of bytes successfully scanned and
processed from src.

.SH EXAMPLES
scan_uuencoded("&9FYO<F0*",buf,&i) -> return 9, i=5, buf="fnord"
