.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. dest can be src.

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".
