In the C tdmext.h header file, the structure for the process-extension parameter is defined

as:

#if defined (__LP64) || defined (_PROCEX32_64BIT)

typedef struct process_extension {

short pe_ver;

short pe_len;

int pe_pfs_size;

long long pe_mainstack_max;

long long pe_heap_max;

long long pe_space_guarantee;

char _ptr64 *pe_library_name;

char _ptr64 *pe_swap_file_name;

char _ptr64 *pe_extswap_file_name;

char _ptr64 *pe_process_name;

char _ptr64 *pe_hometerm;

char _ptr64 *pe_defines;

short pe_defines_len;

short pe_priority;

short pe_cpu;

short pe_memory_pages;

short pe_jobid;

short pe_name_options;

short pe_create_options;

short pe_debug_options;

short pe_OSS_options;

char filler_1[6];

} process_extension_def;

#else /* !defined(__LP64) && !defined (_PROCEX32_64BIT) */

typedef struct process_extension {

long pe_len;

char *pe_library_name;

char *pe_swap_file_name;

char *pe_extswap_file_name;

short pe_priority;

short pe_cpu;

short pe_jobid;

short pe_create_options;

char filler_2[2];

char *pe_defines;

short pe_defines_len;

short pe_name_options;

char filler_1[2];

char *pe_process_name;

char *pe_hometerm;

short pe_memory_pages;

short pe_debug_options;

long pe_pfs_size;

short pe_OSS_options;

char filler_3[2];

When an application is using the #define _PROCEX32_64BIT 1 feature test macro, or an equivalent

compiler command option, the application will have a new version of the process_extension

structure that contains 64-bit data types. The _PROCEX32_64BIT flag is only needed if a 32-bit

process needs to specify larger 64-bit values for pe_mainstack_max, pe_heap_max, and

pe_space_guarantee. These larger data types are optionally used when creating a 64-bit process.

C programs must initialize the process_extension structure by using the #define

DEFAULT_PROCESS_EXTENSION in the tdmext.h header file.
