If the syntax is:
"string"(language)
then we need to verify that the token we've read starts and ends with "(" and ")".

Parse the value string into a buffer, don't copy/move stuff around. The buffer just needs to be 32767 bytes, e.g.:
unsigned char data[32767], *dataptr = data;
char *valptr = value + 1;
do
{
while (isxdigit(valptr[0]) && isxdigit(valptr[1]))
{
// Decode hex digits and store in *dataptr;
valptr += 2;
dataptr ++;
if (dataptr >= (data + sizeof(data))
break;
}
if (*valptr == '>')
break;
else if (*valptr)
{
report_error(...);
return (0);
}
if (!_ippFileReadToken(f, value, sizeof(value))
{
report_error(...);
return (0);
}
valptr = value;
}
// data contains data, "dataptr - data" contains length

Use the same code for IPP_TAG_NAMELANG and IPP_TAG_TEXTLANG (with the two case statements together feeding into the same code).

Need "tolower" here, as "isxdigit" allows upper and lowercase letters.

Don't you need to read another token here?

Hi!
For input like "my string"(language), the var, value, at line 695, initially contains 'my string' , which then is fed into string.text.
Next a token i.e. (language) is read into var value at line 696, which then is fed into string.language.
I don't think another token needs to be read here, is it ?
Minor changes in parse_value()

Holding for later merge, pending other upstream changes coming into libcups. |

A modified version of the changes has been accepted into upstream. The other changes will need to wait for a future CUPS release, sorry... |
