Function Documentation

void openvas_append_string ( gchar **  var,
const gchar *  string 
)

Append a string to a string variable.

When the variable is NULL store a copy of the given string in the variable.

When the variable already contains a string replace the string with a new string that is the concatenation of the two, freeing the old string. It is up to the caller to free the given string if it was dynamically allocated.

Parameters
[in]varThe address of a string variable, that is, a pointer to a string.
[in]stringThe string to append to the string in the variable.
void openvas_append_text ( gchar **  var,
const gchar *  string,
gsize  length 
)

Append a string of a known length to a string variable.

When the variable is NULL store a copy of the given string in the variable.

When the variable already contains a string replace the string with a new string that is the concatenation of the two, freeing the old string. It is up to the caller to free the given string if it was dynamically allocated.

The string must be NULL terminated, and the given length must be the actual length of the string.

Parameters
[in]varThe address of a string variable, that is, a pointer to a string.
[in]stringThe string to append to the string in the variable.
[in]lengthThe length of string.
void openvas_free_string_var ( string var)

Free a string variable.

Free the string in the variable and set the variable to NULL.

Parameters
[in]varThe address of a string variable, that is, a pointer to a string.
char* openvas_strip_space ( char *  string,
char *  end 
)

"Strip" space and newline characters from either end of some memory.

Return the given pointer moved forward past any spaces, replacing the first of any contiguous spaces at or before the end of the memory with a terminating NULL.

This is for use when string points into a static buffers.

Parameters
[in,out]stringThe start of the memory.
[in]endPointer to the byte after the end of the memory.
Returns
A new pointer into the string.
