strchrstrstr

strchrstrstr is a hypothetical function combining the functionalities of two standard C library string manipulation functions, strchr and strstr. In a real-world scenario, such a combined function would not exist in standard C. However, for the purpose of illustration, we can consider its potential behavior.

The strchr function searches a string for the first occurrence of a specific character. It returns a pointer to that character within the string, or a null pointer if the character is not found. The strstr function, on the other hand, searches a string for the first occurrence of an entire substring. It returns a pointer to the beginning of the first occurrence of the substring, or a null pointer if the substring is not found.

A hypothetical strchrstrstr function might be designed to perform both tasks. It could potentially take a string and a search pattern as input. If the search pattern is a single character, it would behave like strchr. If the search pattern is a string of multiple characters, it would behave like strstr. The function's return value would likely indicate the position of the found character or substring, or signal failure. The exact implementation and return conventions would depend on the specific design goals, but the aim would be to provide a more versatile string searching mechanism in a single call. This could offer convenience by reducing the need for multiple, separate function calls in certain programming contexts.
