STRTON(3)

💖 NAME 💖

okay so bestie, welcome to STRTON(3) — this icon converts a string to a long integer, and honestly she’s giving parser main-character energy ✨

🌸 SYNOPSIS 🌸

long strton(char* s, char** e)

🎀 DESCRIPTION 🎀

strton converts the nul-terminated string s to a long integer. If e is not 0, then *e gets set to point to the first unrecognized character in s. Leading spaces in s are ignored — yes, she’s polite like that 💅

A number is composed of sign-base-number-suffix. All of those parts except number are optional, so don’t panic. The sign may be + or -.

The base may be:

• 0x — for hexadecimal;
• 0 — for octal; or
• nn# — for base 2 ≤ nn ≤ 36.

For bases greater than 10, the additional digits are taken from the set [a-zA-Z] — lowercase and uppercase both pulling up, periodt 👑

The suffix multiplies the converted number and may be:

• b — block (512)
• g — giga (1024 * 1024 * 1024)
• k — kilo (1024)
• m — mega (1024 * 1024)
