QUESTION:
1) - WHEN DECLARING TABLES IN C, PUTTING THE DEFINES BEFORE THE FIRST
FUNCTION MAKES THEM GLOBAL. IS THERE A WAY TO DECLARE THEM LOCALLY
TO EACH FUNCTION TO CONSERVE MEMORY?
2) - WHEN A PROCESS FORKS A CHILD PROCESS AND THAT PARENT HAS A DB
CONNECTION , DOES THE CHILD ALSO HAVE A CONNECTION?
---------- ---------- ---------- --------- ---------- ----------
A: This is discussed on page 140 of the Programming Referece Manual,
Publication Number SC09-1573-00. You are referencing the host variable
declarations which correspond to the table items. The precompiler
considers host variables as global to a module. Therefore, host
variable names must be unique within a module, even if they are local to
a function. After the application is precompiled, host variables are
used by the compiler as any other C variable and the same rules apply.
Database access is on a "process level". Therefore, the child will not
inherit the DB connection even if the parent has such a DB connection.
Thank you.
