Walter,
Since I just finished pulling a pile of hair out on a similar, although not
identical, problem yesterday he might look to see if things are the same. In
Pro*C we use a data type called a VARCHAR inside the Oracle declare section.
Something like:
EXEC SQL BEGIN DECLARE SECTION;
VARCHAR name[50];
EXEC SQL END DECLARE SECTION;
When you run it through the precompiler that changes to:
struct
{
char arr[50];
int len;
}name;
A common problem is to forget that 'name' actually has to be referenced as
'name.arr' in C. My problem was:
sprintf(msg, "%s\0", name);
Instead of
sprintf(msg, "%s\0", name.arr);
Also Pro*C does NOT null terminate character strings when they are returned. A
common thing to do is: name.arr[name.len] = '\0'. Your friend may not have null
terminated things, although since it's an fgets() call it's probably not that.
Probably more like:
fgets(name, sizeof(name), fp);
Instead of:
fgets(name.arr, sizeof(name.arr), fp);

>From a fellow employee of mine:
"I am in the process of upgrading from an Oracle 7.3.4 environment using
Pro*C and an HP 32-bit C Compiler (version A.10.32) to an Oracle 8.1.7
64-bit environment using 64-bit Pro*C and a GNU (gcc) 64-bit C Compiler.
All software is on an HP UNIX version 11.00 box.
Specifically, during runtime I am experiencing a SEGMENTATION Fault on the
/usr/lib/libc.2 library when the program executes a fgets() C-statement.
"
Is this obvious to the initiated? Thanks for any help.
The only thing worse in the world than being talked about is not being
talked about.
