USELIB

uselib − select shared library

#include <unistd.h>

int uselib(const char *library);

uselib selects the shared library binary that will be used by the calling process.

On success, zero is returned. On error, −1 is returned, and errno is set appropriately.

In addition to all of the error codes returned by open(2) and mmap(2), the following may also be returned:

ENOEXEC

The file specified by library is not executable, or does not have the correct magic numbers.

EACCES

The library specified by library is not readable.

uselib() is Linux specific, and should not be used in programs intended to be portable.
