Like the libc function, but malloc()'s the space needed.

Parameters:

str

"name=value" string

Returns:

0 on success

int dosetenv	(	const char *	name,
		const char *	value,
		int	overwrite
	)

Like the libc function, but malloc()'s the space needed.

Parameters:

	name	variable name
	value	variable value
	overwrite	should an existing variable be changed?

Returns:

0 on success

list

)

Free split string argv array.

Parameters:

list

argv array

int makeTempFile	(	const char *	prefix,
		const char **	fnptr,
		FD_t *	fdptr
	)

Return file handle for a temporaray file.

A unique temporaray file path will be generated using rpmGenPath(prefix, "%{_tmppath}/", "rpm-tmp.XXXXX") where "XXXXXX" is filled in using rand(3). The file is opened, and the link count and (dev,ino) location are verified after opening. The file name and the open file handle are returned.

Parameters:

prefix

leading part of temp file path

Return values:

	fnptr	temp file name (or NULL)
	fdptr	temp file handle

Returns:

0 on success

rpmRC rpmMkdirPath	(	const char *	dpath,
		const char *	dname
	)

Create directory if it does not exist, and make sure path is writable.

Note:

This will only create last component of directory path.

Parameters:

	dpath	directory path
	dname	directory use string

Returns:
