Function
GLibfile_get_contents
Declaration
gboolean
g_file_get_contents (
const gchar* filename,
gchar** contents,
gsize* length,
GError** error
)
Description
Reads an entire file into allocated memory, with good error checking.
If the call was successful, it returns TRUE and sets contents to the file
contents and length to the length of the file contents in bytes. The string
stored in contents will be nul-terminated, so for text files you can pass
NULL for the length argument. If the call was not successful, it returns
FALSE and sets error. The error domain is G_FILE_ERROR. Possible error
codes are those in the GFileError enumeration. In the error case,
contents is set to NULL and length is set to zero.

g_free()to free the returned string.The argument will be set by the function. The length of the array is specified in the lengthargument.The called function takes ownership of the data, and is responsible for freeing it. length-
Type:
gsize*Location to store length in bytes of the contents, or
NULL.The argument will be set by the function. The argument can be set to NULLby the function. error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will left initialized to NULLby the function if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
