// bin2c.c

|
|
// convert a binary file into a C source vector
|
|
//
|
|
// put into the public domain by Sandro Sigala
|
|
//
|
|
// syntax: bin2c [-c] [-z] <input_file> <output_file>
|
|
//
|
|
// -c add the "const" keyword to definition
|
|
// -z terminate the array with a zero (useful for embedded C strings)
|
|
//
|
|
// examples:
|
|
// bin2c -c myimage.png myimage_png.cpp
|
|
// bin2c -z sometext.txt sometext_txt.cpp
