I wrote a simple c stored procedure that accepts only one text parameter
that i want to convert to a c string.
The problem is that i obtain the C string correctly but with spurious
characters at the end... I use these calls to obtain the c string:
The data in a text datum is not null terminated. You need to call the
function textout() to convert. Grep the source code for examples of invoking
it.
I found these defines into the contrib section:
#define GET_STR(textp) DatumGetCString(DirectFunctionCall1(textout, PointerGetDatum(textp)))
#define GET_TEXT(cstrp) DatumGetTextP(DirectFunctionCall1(textin, CStringGetDatum(cstrp)))
So i can safely use them to obtain a string pointer from a text pointer and viceversa.
I tried and all seemed to work ok.
Thank you,
Denis
