Hello.
Assume that we have a configure option, --disable-foo, with the effect
of setting the symbol NETSNMP_DISABLE_FOO.
Further assume that the foo routines are part of snmplib.
Which version of disabling is the better one:
A)
---foo.h---
extern void foo();
---foo.c---
#ifdef NETSNMP_DISABLE_FOO
void foo() { }
#else
void foo() { /* do foo things */ }
#endif
B)
---foo.h---
#ifdef NETSNMP_DISABLE_FOO
#define foo()
#else
extern void foo();
#endif
---foo.c---
#ifndef NETSNMP_DISABLE_FOO
void foo() { /* do foo things */ }
#endif
C)
---foo.h---
#ifndef NETSNMP_DISABLE_FOO
extern void foo();
#endif
---foo.c---
#ifndef NETSNMP_DISABLE_FOO
void foo() { /* do foo things */ }
#endif
The real case I have is NETSNMP_DISABLE_DEBUG where I am pondering to
either remove or minimize the logging functions.
Anyhow I plan to outright remove the debug_num_tokens and dbg_tokens
symbols (once more defending myself with the "internal" comment above
them) in the DISABLE_DEBUG case.
