64-Bit Environments

Compiling a program to run in a 64-bit operating environment (that is, compiling with -xarch=v9 or v9a and running the executable on a SPARC platform running the 64-bit enabled Solaris 7 operating environment) changes the return values of certain functions. These are usually functions that interface standard system-level routines, such as malloc() (see "malloc, malloc64: Allocate Memory and Get Address"), and may take or return 32-bit or 64-bit values depending on the environment. To provide portability of code between 32-bit and 64-bit environments, 64-bit versions of these routines have been provided that always take and/or return 64-bit values. The following table identifies library routine provided for use in 64-bit environments:
