.TH "BLOB2C" 1 "2024-04-28" "0.2.1" "Urchlay's Atari 8-bit Tools"
.SH NAME
blob2c \- Create C source and header files from a binary file
.\" RST source for blob2c(1) man page. Convert with:
.
.\" rst2man.py blob2c.rst > blob2c.1
.
.\" rst2man.py comes from the SBo development/docutils package.
.
.SH SYNOPSIS
.sp
blob2c \fIblobfile\fP > \fIoutput.c\fP 2> \fIoutput.h\fP
.SH DESCRIPTION
.sp
\fBblob2c\fP prints a C source file to standard output, containing
\fIan unsigned char\fP array, initialized to the contents of \fIblobfile\fP,
and an \fIint\fP, initialized to the length of \fIblobfile\fP in bytes.
.sp
The name of the array is based on the input filename, with
non\-alphanumeric characters replaced by underscores. The name of the
int is the array name, plus the string \fB_len\fP\&.
.sp
Also, a header file containing a pair of extern declarations is
printed to standard error output. This header may be included multiple
times in the same translation unit, since it contains "guard"
preprocessor code to prevent multiple declarations.
.sp
\fBblob2c\fP takes no options, and requires exactly one argument (the
input filename \fIblobfile\fP).
.sp
Exit status is zero for success and non\-zero for failure. Error
messages are printed to standard error output as preprocessor
\fB#error\fP directives, since standard error is expected to be
redirected to a header file. The \fB#error\fP directives will cause the
error messages to be printed when the header file is compiled.
.sp
Although it\(aqs distributed with the author\(aqs Atari 8\-bit
utilities, there\(aqs nothing Atari\-specific about \fBblob2c\fP\&. It could be
useful for any situation where you need to include a file\(aqs contents
as an array in a C program.
