Dynamic link library loading method and apparatus

An electronic device comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory and configured to execute the instructions to cause the electronic device to:
• receive a first request of an application program for loading a first dynamic link library;
• determine, in response to receiving the first request, whether an identifier of the first dynamic link library is in a list of loaded dynamic link libraries;
• and
• perform step A, step B, and step C when the identifier is not in the list C,
• wherein step A comprises allocating a handle to the first dynamic link library and add the identifier and the handle to the list,
• wherein step B comprises determining whether the first dynamic link library is an integrated dynamic link library and performing step 1 and step 2 in sequence when the first dynamic link library is the integrated dynamic link library,
• wherein step 1 comprises adding identifiers of M dynamic link libraries for integration and the handle to the list, wherein the first dynamic link library is based on source code of the M dynamic link libraries;
• and wherein M is a positive integer greater than one, and
• wherein step 2 comprises relocating the first dynamic link library based on the handle, and loading the first dynamic link library into a running memory of the electronic device;
• and
• wherein step C comprises returning the handle to the application program.

A computer program product comprising computer-executable instructions stored on a non-transitory computer readable storage medium that, when executed by a processor, cause an electronic device to:

• receive a first request of an application program for loading a first dynamic link library;
• determine, in response to receiving the first request, whether an identifier of the first dynamic link library is in a list of loaded dynamic link libraries;
• and
• perform step A, step B, and step C when the identifier is not in the list,
• wherein step A comprises allocating a handle to the first dynamic link library and adding the identifier and the handle to the list,
• wherein step B comprises determining whether the first dynamic link library is an integrated dynamic link library and performing step 1 and step 2 in sequence when the first dynamic link library is the integrated dynamic link library,
• wherein step 1 comprises adding identifiers of M dynamic link libraries for integration and the handle to the list, wherein the first dynamic link library is based on source code of the M dynamic link libraries, and wherein M is a positive integer greater than one, and
• wherein step 2 comprises relocating the first dynamic link library based on the handle and loading the first dynamic link library into a running memory of the electronic device;
• and
• wherein step C comprises returning the handle to the application program.
