No, not nearly all of it -- I have 3200 LOC on top of a 6700 kB library. But those functions, together with 'glue code' for the library, can be compiled into the core application of the Pari library, called GP. So these functions provide stand-alone functionality.
Well, actually that's not true. They are called via this function:
which is itself called by GP. But I thought those functions could be understood in isolation.
Overview:
GP is a programmable calculator; C functions can be exposed directly to the users.
Anything marked "GEN" is a bignum object that interacts with the Pari library.
GEN bfile(GEN, GEN, GEN) can be called by the user with input. It turns the first argument into a filename ("file.txt" -> "file.txt"; 123456 -> "b123456.txt"; 40 -> "b000040.txt"). If the latter two arguments are NULL (in this case, this means the user sent only one argument to the function through GP), then GEN bfile (char*) is called. (The file is first checked to make sure it exists.) Otherwise, this function creates a file at that location and outputs data to it.
GEN bfile(char*) takes a filename, opens the file, and reads in the data, storing it to a GEN object it will pass back to GP

Hi,
I have a string like this,
char str ="This, a sample string.\\nThis is the second line, \\n \\n, we will have one blank line";

I tried "\n", "\\n", either not working.

explain_fgets_or_die
explain_fgets_or_die(3) Library Functions Manual explain_fgets_or_die(3)NAME
explain_fgets_or_die - input of strings and report errors
SYNOPSIS
#include <libexplain/fgets.h>
char *explain_fgets_or_die(char *data, int data_size, FILE *fp);
DESCRIPTION
The explain_fgets_or_die function is used to call the fgets(3) system call. On failure an explanation will be printed to stderr, obtained
from explain_fgets(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_fgets_or_die(data, data_size, fp);
data The data, exactly as to be passed to the fgets(3) system call.
data_size
The data_size, exactly as to be passed to the fgets(3) system call.
fp The fp, exactly as to be passed to the fgets(3) system call.
Returns:
This function only returns on success; data when a line is read, or NULL on end-of-file. On failure, prints an explanation and
exits.
SEE ALSO fgets(3)
input of strings
explain_fgets(3)
explain fgets(3) errors
exit(2) terminate the calling process
