chr3

Overview

$1$2chrescchrescchrescchrescchrescchrescchrescchresc converts and returns the next character constant in the 0-terminated string s. If e is not 0 then *e is set to point to the next character in s on return. 0 is returned and e is not modified when the end of s is reached.

$1$2chrtoichrtoichrtoichrtoichrtoichrtoichrtoichrtoi converts the 0-terminated string s to an int and returns the value. The characters in s are converted in order from the left and shifted into the int value until up to the number of characters in an int is reached. This operation is inherently machine-dependent, but at least its defined in one place.

\ooo

\xxx
