Function Documentation int rte_strsplit (char * string, int stringlen, char ** tokens, int maxtokens, char delim) Takes string 'string' parameter and splits it at character 'delim' up to maxtokens-1 times - to give 'maxtokens' resulting tokens. Like strtok or strsep functions, this modifies its input string, by replacing instances of 'delim' with '\0'. All resultant tokens are returned in the 'tokens' array which must have enough entries to hold 'maxtokens'. Parameters string The input string to be split into tokens stringlen The max length of the input buffer tokens The array to hold the pointers to the tokens in the string maxtokens The number of elements in the tokens array. At most, maxtokens-1 splits of the string will be done. delim The character on which the split of the data will be done Returns The number of tokens in the tokens array. ssize_t rte_strscpy (char * dst, const char * src, size_t dsize) Copy string src to buffer dst of size dsize. At most dsize-1 chars will be copied. Always NUL-terminates, unless (dsize == 0). Parameters dst The destination string. src The input string to be copied. dsize Length in bytes of the destination buffer. Returns The number of bytes copied (terminating NUL-byte excluded) on success. -E2BIG if the destination buffer is too small. rte_errno is set. static __rte_experimental const char * rte_str_skip_leading_spaces (const char * src) [inline], [static] Warning EXPERIMENTAL: this API may change without prior notice. Search for the first non whitespace character. Parameters src The input string to be analysed. Returns The address of the first non whitespace character. Definition at line 142 of file rte_string_fns.h. __rte_experimental size_t rte_basename (const char * path, char * buf, size_t buflen) Warning EXPERIMENTAL: this API may change without prior notice. Provides the final component of a path, similar to POSIX basename function. This API provides the similar behaviour on all platforms, Linux, BSD, Windows, hiding the implementation differences. • It does not modify the input path. • The output buffer is passed as an argument, and the result is copied into it. • Expected output is the last component of the path, or the path itself if it does not contain a directory separator. • If the final component is too long to fit in the output buffer, it will be truncated. • For empty or NULL input paths, output buffer will contain the string '.'. • Supports up to PATH_MAX (BSD/Linux) or _MAX_PATH (Windows) characters in the input path. Parameters path The input path string. Not modified by this function. buf The buffer to hold the resultant basename. Must be large enough to hold the result, otherwise basename will be truncated. buflen The size of the buffer in bytes. Returns The number of bytes that were written to buf (excluding the terminating '\0'). If the return value is >= buflen, truncation occurred. Return (size_t)-1 on error (Windows only) Author Generated automatically by Doxygen for DPDK from the source code. Version 25.11.0 Thu Jun 11 2026 rte_string_fns.h(3)
