XLALSimReadDataFileOpen()

LALFILE * XLALSimReadDataFileOpen

(

const char *

fname

)

Opens a specified data file, searching default path if necessary.

Opens a data file for input with a specified path name. If the path name is an absolute path then this specific file is opened; otherwise, search for the file in paths given in the environment variable LAL_DATA_PATH, and finally search in the installed PKG_DATA_DIR path.

Parameters

[in]

fname

The path of the file to open.

Returns

A pointer to a LALFILE structure or NULL on failure.

XLALSimReadDataFile2Col()

size_t XLALSimReadDataFile2Col	(	double **	xdat,
		double **	ydat,
		LALFILE *	fp
	)

Read a two-column data file.

Read a data file containing two whitespace separated columns of data and create two arrays containing the data in each column. If any line begins with the character '#' then it is ignored.

Parameters

[out]	xdat	The x-data stored in the first column.
[out]	ydat	The y-data stored in the second column.
	fp	Pointer to a LALFILE structure opened for input.

Returns

The number of data points read or <0 if an error occurs.

XLALSimReadDataFileNCol()

size_t XLALSimReadDataFileNCol	(	double **	data,
		size_t *	ncol,
		LALFILE *	fp
	)

Read a multi-column data file.

Read a data file containing multiple whitespace separated columns of data and create an array containing the data. If any line begins with the character '#' then it is ignored. The data is stored in the array in row-major format so that the data sample on row i (beginning with zero) and column j (beginning with zero) is found as the element [i * ncol + j] where ncol is the number of columns.

Parameters

[out]	data	The data stored in row-major order.
[out]	ncol	The number of columns in the data file.
	fp	Pointer to a LALFILE structure opened for input.

Returns

The number of rows read or (size_t)(-1) if an error occurs.
