ltrace

Display dynamic library calls of a process. More information: https://linux.die.net/man/1/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}}
