Hi all,
We have an application using ArcSDE SDK C API to translate our data to ArcGIS SDE geodatabase.
Our application runs OK with ArcSDE SDK 10.0 for years without problems.
When we re-build the same code using ArcSDE SDK 10.2 (64 bits),it is found that the structure allocated by
SE_sql_construct_alloc(1, &sqlc) can not be used. The problem can be reproduced by the code below.
After further investigation,I have noticed that it is the complier option /Zp1 caused the invalid
structure returned. The code below works ok if it is compiled with /Zp8 or /Zp16. It will crash if it is complied with /Zp1.
This indicates ArcSDK SDE 10.2 requies 8 or 16 bytes as the Struct member Alignment, however in
our application we requires 1 byte as the Struct member Alignment.
Can anyone suggest how we solves the conflict?
We don’t have the problem with ArcSDE SDK 10.0.
Any help is much appreciated.
int main(int argc, char* argv[])
{
long rc;
SE_SQL_CONSTRUCT *sqlc;
SE_CONNECTION connection;
rc = SE_connection_create(NULL, "sde:sqlserver:sql_instance", "SDI", NULL, NULL, &error,&connection);
// Allocate an SE_SQL_CONSTRUCT
rc = SE_sql_construct_alloc(1, &sqlc);
sqlc->num_tables = 1;
//the code crahses at the below strcpy, debug shows sqlc->tables[0] invalid
strcpy(sqlc->tables[0], "TEST");
printf("table%s\n", sqlc->tables[0]);
return 0;
}
Best regards,
Youmei
