CHECK_UTILITY_COMPAT(3) FreeBSD Library Functions Manual CHECK_UTILITY_COMPAT(3)

check_utility_compat
determine whether a utility should be compatible

Standard C Library (libc, -lc)

#include <unistd.h>

int
check_utility_compat(const char *utility);

The check_utility_compat() function checks whether utility should behave in a traditional (FreeBSD 4.7-compatible) manner, or in accordance with IEEE Std 1003.1-2001 (“POSIX.1”). The configuration is given as a comma-separated list of utility names; if the list is present but empty, all supported utilities assume their most compatible mode. The check_utility_compat() function first checks for an environment variable named _COMPAT_FreeBSD_4. If that environment variable does not exist, then check_utility_compat() will attempt to read the contents of a symbolic link named /etc/compat-FreeBSD-4-util. If no configuration is found, compatibility mode is disabled.

The check_utility_compat() function returns zero if utility should implement strict IEEE Std 1003.1-2001 (“POSIX.1”) behavior, and nonzero otherwise.

/etc/compat-FreeBSD-4-util
If present, a symbolic link whose expansion gives system-wide default settings for the check_utility_compat() function.

No errors are detected.

The check_utility_compat() function first appeared in FreeBSD 5.0.
