Function Documentation

jas_strdup()

JAS_EXPORT char* jas_strdup

(

const char *

s

)

Create a copy of a null-terminated string.

This function has a behavior similar to the well-known strdup function.

jas_stringtokenize()

JAS_EXPORT int jas_stringtokenize	(	const char *	string,
		const char *	delim,
		char ***	tokens_buf,
		size_t *	max_tokens_buf,
		size_t *	num_tokens_buf
	)

Split a string into tokens based on specified delimiters.

Parameters

string	A pointer to a null-terminated string to be split into tokens.
delim	A pointer to a null-terminated string contained characters used to delimit tokens.
tokens_buf	A pointer to the output token array.
max_tokens_buf	A pointer to the allocated size of the token array.
num_tokens_buf	A pointer to the number of elements in the token array.

The memory to hold token information is allocated via jas_malloc() and friends.

Returns

If successful, zero is returned. Otherwise, a nonzero value is returned.

jas_strtok()

JAS_EXPORT char* jas_strtok	(	char *	str,
		const char *	delim,
		char **	saveptr
	)

Extract tokens from a string.

This function has a similar behavior as strtok_r in the POSIX standard.
