✨ STRSPN(3POSIX) ✨

okay bestie, so this page lives in the POSIX Programmer's Manual (that's the 3POSIX situation right there in the title) 💅

🌸 PROLOG 🌸

Heads up, bestie: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so like, consult the corresponding Linux manual page for the deets on Linux behavior — or honestly the interface may not even be implemented on Linux at all. 😭

👑 NAME 👑

strspn — get length of a substring 🎀

🦋 SYNOPSIS 🦋

#include <string.h>

size_t strspn(const char *s1, const char *s2);

💖 DESCRIPTION 💖

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional, fr fr. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt. 💅

The strspn() function shall compute the length (in bytes) of the maximum initial segment of the string pointed to by s1 which consists entirely of bytes from the string pointed to by s2. 🧚

🌈 RETURN VALUE 🌈

The strspn() function shall return the computed length; no return value is reserved to indicate an error. so like, don't go looking for an error code, it's not there bestie 🙈
