# File System Utilities / `inifile` INI File
|
|
||||||
|
|
||||||
## Syntax
|
|
||||||
|
|
||||||
This directory contains a very simple INI file parser. An INI file consists of a
|
|
||||||
sequence of lines up to the end of file. A line may be one of the following:
|
|
||||||
|
|
||||||
1. A blank line.
|
|
||||||
|
|
||||||
2. A comment line. Any line beginning with `;`
|
|
||||||
|
|
||||||
3. A section header. Definitions are divided into sections. Each section begins
|
|
||||||
with a line containing the section name enclosed in square brackets. For
|
|
||||||
example, `[section1]`. The left bracket must be the first character on the
|
|
||||||
line. Section names are case insensitive, i.e., `SECTION1` and `Section1`
|
|
||||||
refer to the same section.
|
|
||||||
|
|
||||||
4. Variable assignments. A variable assignment is a variable name followed by
|
|
||||||
the `=` sign and then the value of the variable. For example, `A=B`: `A` is
|
|
||||||
the variable name; `B` is the variable value. All variables following the
|
|
||||||
section header belong in the section.
|
|
||||||
|
|
||||||
Variable names may be preceded with white space. Whitespace is not permitted
|
|
||||||
before the `=` sign. Variable names are case insensitive, i.e., `A` and `a`
|
|
||||||
refer to the same variable name.
|
|
||||||
|
|
||||||
Variable values may be numeric (any base) or a string. The case of string
|
|
||||||
arguments is preserved.
|
|
||||||
|
|
||||||
## Programming Interfaces
|
|
||||||
|
|
||||||
See `apps/include/fsutils/inifile.h` for interfaces supported by the INI file
|
|
||||||
parser.
|
|
||||||
|
|
||||||
## Test Program
|
|
||||||
|
|
||||||
Below is a simple test program:
|
|
||||||
|
|
||||||
```c
|
|
||||||
int main(int argc, char *argv[])
|
|
||||||
{
|
|
||||||
INIHANDLE handle;
|
|
||||||
FILE *stream;
|
|
||||||
FAR char *ptr;
|
|
||||||
long value;
|
|
||||||
|
|
||||||
stream = fopen("/tmp/file.ini", "w");
|
|
||||||
fprintf(stream, "; Test INI file\n");
|
|
||||||
fprintf(stream, "[section1]\n");
|
|
||||||
fprintf(stream, " VAR1=1\n");
|
|
||||||
fprintf(stream, " VAR2=2\n");
|
|
||||||
fprintf(stream, " VAR3=3\n");
|
|
||||||
fprintf(stream, "\n");
|
|
||||||
fprintf(stream, "[section2]\n");
|
|
||||||
fprintf(stream, " VAR4=4\n");
|
|
||||||
fprintf(stream, " VAR5=5\n");
|
|
||||||
fprintf(stream, "VAR6=6\n");
|
|
||||||
fprintf(stream, "\n");
|
|
||||||
fclose(stream);
|
|
||||||
|
|
||||||
