Function Documentation

checkFileArg()

int checkFileArg	(	int	name,
		FILE **	filePtr,
		const char *	optArg,
		const char *	mode
	)

Parses command line arguments and fills the CapConfig struct.

Also provides utility functions for checking and parsing arguments.

Checks if the provided argument is a valid file and opens it.

Parameters

name	The name of the argument (for error messages).
filePtr	Pointer to a FILE* that will be set to the opened file.
optArg	The argument string to check (should be a filename).
mode	The mode to open the file (e.g., "r" for read, "w" for write).

Returns

0 on success, non-zero on failure.

checkUIntArg()

int checkUIntArg	(	int	name,
		unsigned int *	value,
		const char *	optArg
	)

Checks if the provided argument is a valid integer and parses it.

Parameters

name	The name of the argument (for error messages).
value	Pointer to an int that will be set to the parsed value.
optArg	The argument string to check (should be an integer).

Returns

0 on success, non-zero on failure.

getDouble()

double getDouble

(

char *

ptr

)

Parses a double from a string.

Parameters

ptr	The string to parse.

Returns

The parsed double value.

getDoublesFromStdin()

int getDoublesFromStdin	(	size_t	maxCount,
		double *	arr
	)

Reads one line from stdin and parses up to maxCount doubles into array.

Reads doubles from standard input until EOF or maxCount is reached.

Returns the number of doubles stored (>=0), or -1 on I/O/memory error.

getInt()

int getInt

(

char *

ptr

)

Parses an integer from a string.

Parameters

ptr	The string to parse.

Returns

The parsed integer value.

getIntsFromFile()

int getIntsFromFile	(	size_t	maxCount,
		int *	arr,
		FILE *	file
	)

Reads integers from file until EOF or maxCount is reached.

Parameters

maxCount	The maximum number of integers to read.
arr	Pointer to an array where the read integers will be stored.
file	Pointer to read integers from

Returns

The number of integers successfully read.

parseArguments()

void parseArguments	(	int	argc,
		char *	argv[],
		CapConfig *	cfg
	)

Parses command line arguments and fills the CapConfig struct.

Parameters

argc	The number of command line arguments.
argv	The array of command line argument strings.
cfg	Pointer to a CapConfig struct that will be filled with the parsed configuration.
