uselib(2)                  System Calls Manual                 uselib(2)

НАЗВАНИЕ

       uselib - load shared library

СИНТАКСИС

       #include <unistd.h>

       [[deprecated]] int uselib(const char *library);

ОПИСАНИЕ

       The system call uselib() serves to load a shared library to be
       used by the calling process.  It is given a pathname.  The
       address where to load is found in the library itself.  The
       library can have any recognized binary format.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, zero is returned.  On error, -1 is returned, and
       errno is set to indicate the error.

ОШИБКИ

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

       EACCES The library specified by library does not have read or
              execute permission, or the caller does not have search
              permission for one of the directories in the path prefix.
              (See also path_resolution(7).)

       ENFILE The system-wide limit on the total number of open files
              has been reached.

       ENOEXEC
              The file specified by library is not an executable of a
              known type; for example, it does not have the correct
              magic numbers.

СТАНДАРТЫ

       Linux.

ИСТОРИЯ

       This obsolete system call is not supported by glibc.  No
       declaration is provided in glibc headers, but, through a quirk of
       history, glibc before glibc 2.23 did export an ABI for this
       system call.  Therefore, in order to employ this system call, it
       was sufficient to manually declare the interface in your code;
       alternatively, you could invoke the system call using syscall(2).

       In ancient libc versions (before glibc 2.0), uselib() was used to
       load the shared libraries with names found in an array of names
       in the binary.

       Since Linux 3.15, this system call is available only when the
       kernel is configured with the CONFIG_USELIB option.
