SNOBOL4HOST(3) | CSNOBOL4B 2.3.2 | Janurary 1, 2024

NAME

SYNOPSIS

-INCLUDE 'host.sno'

DESCRIPTION

HOST()

Macro SPITBOL: returns ARCHITECTURE:OPERATING_SYSTEM:SNOBOL_VERSION The string contains three parts, separated by colons. The first part describes the physical architecture, the second describes the operating system, and the third describes the language implementation name and version. NOTE! Architecture names come from the uname(3) library call, and may be different for the same hardware when running different operating systems. Examples:
    amd64:FreeBSD 12.1-RELEASE-p1:CSNOBOL4B 2.2
    x86_64:Linux 5.4.0-12-generic:CSNOBOL4B 2.2

HOST(0)

Macro SPITBOL: returns a string containing the command line parameter supplied to the -u option, if any. If no -u option was given, HOST(0) returns the concatenation of all user parameters following the input filename(s).

HOST(1, string)

Catspaw SPITBOL: passes the string to the system(3) C library function, and returns the subprocess exit status.

HOST(2, n)

Catspaw SPITBOL: for integer n returns the n'th command line argument (regardless of whether the argument was the command name, an option, a filename or a user parameter) as a string, or failure if n is out of range.

HOST(3)

Catspaw SPITBOL: returns an integer for use with HOST(2) indicating the first command line argument available as a user parameter.

HOST(4, string)

Catspaw SPITBOL: returns the value of the environment variable named by string.
