25 | .SH NAME |
26 | posixoptions \- optional parts of the POSIX standard | |
27 | .SH DESCRIPTION | |
4dec66f9 | 28 | The POSIX standard (the information below is from POSIX.1-2001) |
6beb1671 | 29 | describes a set of behaviors and interfaces for a compliant system. |
fea681da MK |
30 | However, many interfaces are optional and there are feature test macros |
31 | to test the availability of interfaces at compile time, and functions | |
32 | .BR sysconf (3), | |
33 | .BR fpathconf (3), | |
34 | .BR pathconf (3), | |
35 | .BR confstr (3) | |
c13182ef MK |
36 | to do this at run time. |
37 | From shell scripts one can use | |
fea681da MK |
38 | .BR getconf (1). |
39 | For more detail, see | |
40 | .BR sysconf (3). | |
dd3568a1 | 41 | .PP |
fea681da | 42 | We give the name of the POSIX abbreviation, the option, the name of the |
0b80cf56 | 43 | .BR sysconf (3) |
fea681da MK |
44 | parameter used to inquire about the option, and possibly |
45 | a very short description. | |
46 | Much more precise detail can be found in the POSIX standard itself, | |
47 | versions of which can nowadays be accessed freely on the web. | |
