Functions in this namespace
Functions
- getCwd
- The result is a slice of `out_buffer`, from index `0`.
- getCwdAlloc
- Caller must free the returned memory.
- getEnvMap
- Returns a snapshot of the environment variables of the current process.
- getEnvVarOwned
- Caller must free returned memory.
- hasEnvVarConstant
- On Windows, `key` must be valid WTF-8.
- hasNonEmptyEnvVarConstant
- On Windows, `key` must be valid WTF-8.
- parseEnvVarInt
- Parses an environment variable as an integer.
- hasEnvVar
- On Windows, if `key` is not valid [WTF-8](https://simonsapin.github.io/wtf-8/),
- hasNonEmptyEnvVar
- On Windows, if `key` is not valid [WTF-8](https://simonsapin.github.io/wtf-8/),
- getenvW
- Windows-only.
- ArgIteratorGeneral
- A general Iterator to parse a string into a set of arguments
- args
- Holds the command-line arguments, with the program name as the first entry.
- argsWithAllocator
- You must deinitialize iterator's internal buffers by calling `deinit` when done.
- argsAlloc
- Caller must call argsFree on result.
- getUserInfo
- POSIX function which gets a uid from username.
- posixGetUserInfo
- TODO this reads /etc/passwd.
- execv
- Replaces the current process image with the executed process.
- execve
- Replaces the current process image with the executed process.
- totalSystemMemory
- Returns the total system memory, in bytes as a u64.
- cleanExit
- Indicate that we are now terminating with a successful exit code.
- raiseFileDescriptorLimit
- Raise the open file descriptor limit.
- createEnvironFromMap
- Creates a null-delimited environment variable block in the format
- createEnvironFromExisting
- Creates a null-delimited environment variable block in the format
- createWindowsEnvBlock
- Caller must free result.
- fatal
- Logs an error and then terminates the process with exit code 1.
