Detailed Description

WASM initialization helpers implementation.

Shared initialization utilities compiled into both WASM modules.

Function Documentation

wasm_parse_args()

int wasm_parse_args	(	const char *	args_str,
		char **	argv,
		int	max_args,
		char **	out_args_copy
	)

Parse space-separated args_str into argv[] Sets *out_args_copy to the strdup'd buffer that must be freed by the caller AFTER argv is no longer needed (since argv points into args_copy).

Parameters

args_str	Space-separated argument string
argv	Output array to store argument pointers (at least max_args elements)
max_args	Maximum number of arguments to parse
out_args_copy	Output buffer for the strdup'd args_str

Returns

argc (number of arguments parsed), or -1 on allocation failure
