NAME

7

SYNOPSIS

9       #include <dlfcn.h>
10

DESCRIPTION

12       The <dlfcn.h> header shall define at least the following macros for use
13       in the construction of a dlopen() mode argument:
14
15       RTLD_LAZY
16              Relocations are performed at an implementation-defined time.
17
18       RTLD_NOW
19              Relocations are performed when the object is loaded.
20
21       RTLD_GLOBAL
22              All symbols are available for  relocation  processing  of  other
23              modules.
24
25       RTLD_LOCAL
26              All  symbols are not made available for relocation processing by
27              other modules.
28
29
30       The following shall be declared as functions and may also be defined as
31       macros. Function prototypes shall be provided.
32
33
34              int    dlclose(void *);
35              char  *dlerror(void);
36              void  *dlopen(const char *, int);
37              void  *dlsym(void *restrict, const char *restrict);
