Potluck with different functions for different purposes that can be shared among C programs.

This is a small library intended to provide low-level functionalities in my other libraries and programs.

The functionalities are divided into 4 categories:

• Wrappers for string.h: functions like strcpy, strcmp or strchr that will not segfault if a parameter is NULL
• split_string and afiliated functions: split a string using a separator match or join a split string

Simple structure to store and manipulate any kind of pointer in an array.

Encode, decode in base64 and base64url format.

Replace glib malloc/realloc/free functions with user-defined memory functions.
