libfunctions (External Interfaces Reference)

Return information on functions in external library

Syntax

m = libfunctions('libname')
m = libfunctions('libname', '-full')
libfunctions libname -full

Description

m = libfunctions('libname') returns the names of all functions defined in the external shared library, libname, that has been loaded into MATLAB with the loadlibrary function. The return value, m, is a cell array of strings.

If you used an alias when initially loading the library, then you must use that alias for the libname argument.

m = libfunctions('libname', '-full') returns a full description of the functions in the library, including function signatures. This includes duplicate function names with different signatures. The return value, m, is a cell array of strings.

libfunctions libname -full is the command format for this function.

Examples

List the functions in the MATLAB libmx library:

hfile = [matlabroot '\extern\include\matrix.h'];
loadlibrary('libmx', hfile)

libfunctions libmx

       .                      .                  .
       .                      .                  .

To list the functions along with their signatures, use the -full switch with libfunctions:

libfunctions libmx -full

Methods for class lib.libmx:
[mxClassID, MATLAB array] mxGetClassID(MATLAB array)
[lib.pointer, MATLAB array] mxGetData(MATLAB array)
[MATLAB array, voidPtr] mxSetData(MATLAB array, voidPtr)
[uint8, MATLAB array] mxIsNumeric(MATLAB array)
[uint8, MATLAB array] mxIsCell(MATLAB array)
[lib.pointer, MATLAB array] mxGetPr(MATLAB array)
[MATLAB array, doublePtr] mxSetPr(MATLAB array, doublePtr)
         .
         .
