.SH NAME

.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".
