ZstrToI64

ZstrToI64

Description

Parse a signed decimal integer from a null-terminated string. Skips ASCII whitespace, accepts an optional leading sign, then consumes the longest run of 0..9. Base-10 only; callers that need radix-aware parsing reach for the typed StrToI64 / StrToU64 family with a StrParseConfig.

Success

Returns the parsed value as i64. Overflow saturates to INT64_MAX / INT64_MIN.

Failure

Returns 0 when no digits are present.
