310Sstevel@tonic-gate * These routines are based on the standard UNIX stdio popen/pclose
320Sstevel@tonic-gate * routines. This version takes an argv[][] argument instead of a string
330Sstevel@tonic-gate * to be passed to the shell. The routine execvp() is used to call the
340Sstevel@tonic-gate * program, hence the name popenvp() and the argument types.
350Sstevel@tonic-gate *
360Sstevel@tonic-gate * This routine avoids an extra shell completely, along with not having
370Sstevel@tonic-gate * to worry about quoting conventions in strings that have spaces,
380Sstevel@tonic-gate * quotes, etc.
