Function libyml::string::yaml_string_extend

pub unsafe fn yaml_string_extend(
    start: *mut *mut u8,
    pointer: *mut *mut u8,
    end: *mut *mut u8,
)

Extend a string buffer by reallocating and copying the existing data.

This function is used to grow a string buffer when more space is needed.

Safety

• This function is unsafe because it directly calls the system’s realloc and memset functions, which can lead to undefined behaviour if misused.
• The caller must ensure that start, pointer, and end are valid pointers into the same allocated memory block.
• The caller must ensure that the memory block being extended is large enough to accommodate the new size.
• The caller is responsible for properly freeing the extended memory block using the corresponding yaml_free function when it is no longer needed.
