Detailed Description

C-string buffer class.

GATE strings need not to be NUL-terminated, but many C APIs require this convention. A C-string buffer takes a string pointer, and check it for NUL-termination. If it's NUL-terminated, it takes it as it is. Otherwise it checks the length and tries to copy it into a local buffer. If the local buffer is not big enough, a heap allocation is done to copy the string into it. At the end we get a string pointer that points to a NUL-terminated string.

Field Documentation

str

gate_char8_t const* str

actual pointer to NUL-terminated string

length

gate_size_t length

length of NUL-terminated string (not counting the NUL char)

heap_buffer

gate_char8_t* heap_buffer

optional point to heap-allocated string (for deletion)

local_buffer

gate_char8_t local_buffer[GATE_DEFAULT_LINE_LENGTH]

< optional local buffer for NUL-terminated string
