Reading input line by line is a common requirement in C programming. Thegetlinefunction provides a robust solution for this task, automatically handling memory allocation. This tutorial explains how to usegetlineeffectively, covering its parameters, return values, and memory management. With practical e...
Now that you’ve fixed the pointer handling, check if the segmentation fault still occurs. If it does, we can investigate further into theFPIMatch()function or other memory management issues in your code. Below is a simple implementation of thegetline()function. It won’t be as optimized as...
The getline function is used to read a stream. getline uses parameters that require you to use the stdio.h header file (included in the standard C library). One of the variables within the stdio.h library that will be used is the size_t variable, which will be discussed in the “...
n-pointer to the size of the initial buffer delimiter-the delimiter character stream-valid input stream, opened byfopen Return value The number of characters stored in the buffer, including the delimiter, but excluding the null terminator.

This is effectively a port of libpam's _pam_assemble_line function found in pam_handlers.c. Noteworthy differences to keep old behavior: The backslash of escaped newline is NOT replaced by a blank Clears buffer (overwrites everything with \0) in _pam_buffer_clear This affects pam_env onl...
