.SH NAME
scan_jsonescape \- parse JSON escaped string
.SH SYNTAX
.B #include <libowfat/textcode.h>

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

.SH DESCRIPTION
scan_jsonescape parses JSON escaped text from src into dest, leaving a
UTF-8 string in dest. Parsing stops at the 0 terminator, invalid input
characters or a double quote that was not escaped.

It will then write the number of bytes in dest into *destlen,
and return the number of bytes decoded from src.

dest can be NULL. destlen can be NULL.

To make sure dest is large enough, either allocate strlen(src)+1 bytes
or call scan_jsonescape twice, the first time with dest == NULL (*destlen
will still be written).

.SH "RETURN VALUE"
scan_jsonescape returns the number of bytes successfully parsed
from src.

.SH EXAMPLES
scan_jsonescape("test\n\");",buf,&i) -> return 6, i=5, buf="test\n".
