-.TH get_kernel_syms 2 2023-10-31 "Linux man-pages 6.7"
-.SH NAME
-get_kernel_syms \- retrieve exported kernel and module symbols
-.SH SYNOPSIS
-.nf
-.B #include <linux/module.h>
-.P
-.BI "[[deprecated]] int get_kernel_syms(struct kernel_sym *" table );
-.fi
-.SH DESCRIPTION
-.BR Note :
-This system call is present only before Linux 2.6.
-.P
-If
-.I table
-is NULL,
-.BR get_kernel_syms ()
-returns the number of symbols available for query.
-Otherwise, it fills in a table of structures:
-.P
-.in +4n
-.EX
-struct kernel_sym {
- unsigned long value;
- char name[60];
-};
-.EE
-.in
-.P
-The symbols are interspersed with magic symbols of the form
-.BI # module-name
-with the kernel having an empty name.
-The value associated with a symbol of this form is the address at
-which the module is loaded.
-.P
-The symbols exported from each module follow their magic module tag
-and the modules are returned in the reverse of the
-order in which they were loaded.
-.SH RETURN VALUE
-On success, returns the number of symbols copied to
-.IR table .
-On error, \-1 is returned and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-There is only one possible error return:
-.TP
-.B ENOSYS
-.BR get_kernel_syms ()
-is not supported in this version of the kernel.
-.SH STANDARDS
-Linux.
-.SH HISTORY
-Removed in Linux 2.6.
-.\" Removed in Linux 2.5.48
-.P
-This obsolete system call is not supported by glibc.
-No declaration is provided in glibc headers, but, through a quirk of history,
-glibc versions 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
-.BR syscall (2).
-.SH BUGS
-There is no way to indicate the size of the buffer allocated for
-.IR table .
-If symbols have been added to the kernel since the
-program queried for the symbol table size, memory will be corrupted.
-.P
-The length of exported symbol names is limited to 59 characters.
-.P
-Because of these limitations, this system call is deprecated in
-favor of
-.BR query_module (2)
-(which is itself nowadays deprecated
-in favor of other interfaces described on its manual page).
