- get configurable variables
#include <unistd.h>size_tconfstr(intname,char *buf,size_tlen);
Theconfstr() function provides a method for applications to get configuration-defined string values. Its use and purpose are similar to thesysconf(3C) function, butit is used where string values rather than numeric values are returned.
Thename argument represents the system variable to be queried.
Iflen is not0, and ifname has a configuration-defined value,confstr() copies that value into thelen-byte buffer pointed to bybuf. If the string to be returned is longer thanlen bytes, includingthe terminating null, thenconfstr() truncates the string tolen-1 bytesand null-terminates the result. The application can detect that the string wastruncated by comparing the value returned byconfstr() withlen.
Iflen is0,confstr() still returns the integer value as definedbelow, but does not return the string.
Theconfstr() function supports the following values forname, defined in<unistd.h>,for both SPARC and x86:

Ifname has a configuration-defined value, theconfstr() function returns the sizeof buffer that would be needed to hold the entire configuration-defined value. If this return value is greater thanlen, the string returnedinbuf is truncated.
Ifname is invalid,confstr() returns0 and setserrno toindicate the error.
Ifname does not have a configuration-defined value,confstr() returns0and leaveserrno unchanged.
