Group PJ_SYS_INFO

group PJ_SYS_INFO

Enums

enum pj_sys_info_flag

These enumeration contains constants to indicate support of miscellaneous system features. These will go in “flags” field of pj_sys_info structure.

Values:

enumerator PJ_SYS_HAS_IOS_BG

Support for Apple iOS background feature.

Functions

const pj_sys_info *pj_get_sys_info(void)

Obtain the system information.

Returns:

System information structure.

struct pj_sys_info

#include <os.h>

This structure contains information about the system. Use pj_get_sys_info() to obtain the system information.

Public Members

pj_str_t machine

Null terminated string containing processor information (e.g. “i386”, “x86_64”). It may contain empty string if the value cannot be obtained.

pj_str_t os_name

Null terminated string identifying the system operation (e.g. “Linux”, “win32”, “wince”). It may contain empty string if the value cannot be obtained.

pj_uint32_t os_ver

A number containing the operating system version number. By convention, this field is divided into four bytes, where the highest order byte contains the most major version of the OS, the next less significant byte contains the less major version, and so on. How the OS version number is mapped into these four bytes would be specific for each OS. For example, Linux-2.6.32-28 would yield “os_ver” value of 0x0206201c, while for Windows 7 it will be 0x06010000 (because dwMajorVersion is 6 and dwMinorVersion is 1 for Windows 7).

This field may contain zero if the OS version cannot be obtained.

pj_str_t sdk_name

Null terminated string identifying the SDK name that is used to build the library (e.g. “glibc”, “uclibc”, “msvc”, “wince”). It may contain empty string if the value cannot eb obtained.

pj_uint32_t sdk_ver

A number containing the SDK version, using the numbering convention as the “os_ver” field. The value will be zero if the version cannot be obtained.

pj_str_t info

A longer null terminated string identifying the underlying system with as much information as possible.

pj_uint32_t flags

Other flags containing system specific information. The value is bitmask of pj_sys_info_flag constants.
