The result is +/* a null-terminated string array. +/* +/* argv_split_count() is like argv_split() but stops splitting +/* input after at most \fIcount\fR -1 times and leaves the +/* remainder, if any, in the last array element. It is an error +/* to specify a count < 1. +/* +/* argv_split_append() performs the same operation as argv_split(), +/* but appends the result to an existing string array. +/* SEE ALSO +/* mystrtok(), safe string splitter. +/* DIAGNOSTICS +/* Fatal errors: memory allocation problem. +/* LICENSE +/* .ad +/* .fi +/* The Secure Mailer license must be distributed with this software. +/* AUTHOR(S) +/* Wietse Venema +/* IBM T.J.
