ZIP_SOURCE_FILE(3)					     Library Functions Manual						ZIP_SOURCE_FILE(3)

NAME
zip_source_file - create data source from a file LIBRARY
libzip (-lzip) SYNOPSIS
struct zip_source * zip_source_file(struct zip *archive, const char *fname); "zip_uint64_t start" "zip_int64_t len" DESCRIPTION
The function zip_source_file creates a zip source from a file. zip_source_file opens fname and reads len bytes from offset start from it. If len is 0 or -1, the whole file (starting from start ) is used. The fie is opened and read when the data from the source is used, usually by zip_close. RETURN VALUES
Upon successful completion, the created source is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error. ERRORS
zip_source_file fails if: [ZIP_ER_INVAL] fname, start, or len are invalid. [ZIP_ER_MEMORY] Required memory could not be allocated. [ZIP_ER_OPEN] Opening fname failed. SEE ALSO
