Function Documentation

file_memory_load()

void* file_memory_load	(	FILE *	f,
		int64_t *	f_size_p
	)

Load a whole file content in a mm_alloc-ed memory buffer.

Parameters

[in]	f	the file to load
[out]	f_size_p	a pointer to a variable which will contain with the loaded file size

Returns

a mm_alloc-ed buffer filled in with the file content, or NULL if a read error happened

file_open()

FILE* file_open	(	const char *	open_type,
		const char *	fmt,
			...
	)

A version of fopen() which accepts a printf style format string.

Parameters

open_type	a string which controls how the file is opened (see fopen())
fmt	the file name expressed as a printf style format string
...	the list of additional arguments used in fmt (see printf())

file_write_chunk()

static void file_write_chunk ( FILE *  f, const void *  data, size_t  data_size  )

inlinestatic

Write the content of a memory buffer in a file.

Parameters

[in]	f	the file to write
[in]	data	a pointer to the memory buffer containing the data to write to the file
[in]	data_size	the size of the memory buffer pointed by data

Very stupid convenience function which does basic error handling on the actual fwrite() call.
