dlget(3C)dlget(3C)NAMEdlget() - retrieve information about a loaded module (program or shared
library)
SYNOPSIS
[flag]... file... [library]...
Multithread Usage
This routine is thread-safe.
DESCRIPTION
is one of a family of routines that give the user direct access to the
dynamic linking facilities. returns information about a loaded module
for a process. retrieves information about a load module from an index
specifying the placement of the load module in the dynamic loader's
search list. An index of requests information about the dynamic
loader. An index of requests information about the program file
itself.
If successful, returns a handle for the shared library as defined by
the return value from
desc must be preallocated by the user. The structure members are
filled in by the dynamic loader with information about the requested
shared library.
A load_module_desc structure has the following members:
struct load_module_desc {
unsigned long text_base;
unsigned long text_size;
unsigned long data_base;
unsigned long data_size;
unsigned long unwind_base;
unsigned long linkage_ptr;
unsigned long phdr_base;
unsigned long tls_size;
unsigned long tls_start_addr;
}
desc_size specifies the size in bytes of the load_module_desc structure
sent in by the user.
If a call to is unsuccessful, a NULL pointer is returned and desc
remains unchanged.
ERRORS
If fails, a subsequent call to returns one of the following values:
Cannot apply relocation in library.
Invalid descriptor argument.
Invalid descriptor version.
Invalid load module index.
Out of memory.
