ltrace

Display dynamic library calls of a process. More information: https://manned.org/ltrace.

• Print (trace) library calls of a program binary:

ltrace ./program

• Count library calls. Print a handy summary at the bottom:

ltrace -c path/to/program

• Trace calls to malloc and free, omit those done by libc:

ltrace -e malloc+free-@libc.so* path/to/program

• Write to file instead of terminal:

ltrace -o file path/to/program
