#define PRISM_ATTRIBUTE_FORMAT(string_index, argument_index)
Certain compilers support specifying that a function accepts variadic parameters that look like print...
#define PRISM_EXPORTED_FUNCTION
By default, we compile with -fvisibility=hidden.
A pm_buffer_t is a simple memory buffer that stores data in a contiguous block of memory.
size_t capacity
The capacity of the buffer in bytes that has been allocated.
size_t length
The length of the buffer in bytes.
char * value
A pointer to the start of the buffer.
